What does 1 Peter 1:20 Mean?

Study Notes

foreordained
The divine order is foreknowledge, election, predestination. That foreknowledge determines the election or choice is clear from 1 Peter 1:2 and predestination is the bringing to pass of the election. "election looks back to foreknowledge; predestination forward to the destiny." But Scripture nowhere declares what it is in the divine foreknowledge which determines the divine election and predestination. The foreknown are elected, and the elect are predestinated, and this election is certain to every believer by the mere fact that he believes 1 Thessalonians 1:4 ; 1 Thessalonians 1:5
See Predestination .
predestinated
Predestination is that effective exercise of the will of God by which things before determined by Him are brought to pass. See Election,
(See Scofield " 1 Peter 1:2 ")
Foreknowledge, (See Scofield " 1 Peter 1:20 ")
adoption
Adoption (huiothesia, "placing as a son") is not so much a word of relationship as of position. The believer's relation to God as a child results from the new birth John 1:12 ; John 1:13 whereas adoption is the act of God whereby one already a child is, through redemption from the law, placed in the position of an adult son. Galatians 4:1-5 .
The indwelling Spirit gives the realization of this in the believer's present experience Galatians 4:6 but the full manifestation of the believer's sonship awaits the resurrection, change, and translation of saints, which is called "the redemption of the body"; Romans 8:23 ; 1 Thessalonians 4:14-17 ; Ephesians 1:14 ; 1 John 3:2 .

Context Summary

1Pe 1:13-25 - Redeemed And Purified
The appeal for a holy life is enforced by considering the great cost of our redemption and the great hope which is opened before us. Ours must be the girded loins, lest our desires trail after forbidden things, or be sullied by the mud on the road. We must be holy, as God is: and this can be realized only when we allow God, by His Holy Spirit, to pour Himself into our natures.
There is no fear like that which love begets. We do not fear God with the fear of the slave or felon, but with the fear of the love that cannot endure the thought of giving pain to the loving and loved. Who can think of returning to Egypt, when such a Passover lamb has redeemed us! Our redemption was not an after-thought with God. It is part of an eternal plan; let us not get entangled in the meshes of mere earthly ambition. Notice the familiar combination of faith, hope and love, 1 Peter 1:21-22. But these graces are only indigenous in those who have been twice born by the Spirit through the Word. [source]

Greek Commentary for 1 Peter 1:20

Who was foreknown indeed [προεγνωσμενου μεν]
Perfect passive participle (in genitive singular agreeing with Χριστου — Christou) of προγινωσκω — proginōskō old verb, to know beforehand (Romans 8:29; 2 Peter 3:17). See προγνωσιν τεου — prognōsin theou in 1 Peter 1:2. [source]
Before the foundation of the world [προ καταβολης κοσμου]
This precise curious phrase occurs in John 17:24 in the Saviour‘s mouth of his preincarnate state with the Father as here and in Ephesians 1:4. We have απο καταβολης κοσμου — apo katabolēs kosmou in Matthew 25:34 The preincarnate Messiah appears in the counsels of God also in 1 Corinthians 2:7; Colossians 1:26.; Ephesians 1:9.; Ephesians 3:9-11; Romans 16:25; 1 Timothy 1:9.But was manifested (πανερωτεντος δε — phanerōthentos de). First aorist (ingressive) passive participle of πανεροω — phaneroō referring to the Incarnation in contrast with the preexistence of Christ (cf. John 1:31; 1 John 3:5, 1 John 3:8).At the end of the times Like επ εσχατου των ημερων — ep' eschatou tōn hēmerōn (Hebrews 1:2). The plural χρονοι — chronoi doubtless referring to successive periods in human history until the fullness of the time came (Galatians 4:4).For your sake (δι υμας — di' humās).

John 21:1 Shewed [ἐφανέρωσεν]
This rendering might easily convey merely the sense of appearing; but its meaning is much deeper. Occurring frequently in the New Testament, it is used most frequently of God and Christ, or of men in their relation to these. Thus, of Christ in person while upon earth (Mark 16:12, Mark 16:14; John 1:31; John 2:11; 1 Peter 1:20; 1 John 1:2). Of the works of Christ (John 2:11; John 9:3; 1 John 3:5). Of Christ in redemption (1 John 3:5). Of Christ in His second coming (1 John 2:28). Of Christ in glory (1 John 3:2; Colossians 3:4). It is used of God. Of His revelation to men of the knowledge of Himself (Romans 1:19). Of His manifestation in Christ (1 Timothy 3:16). Of His righteousness (Romans 3:21). Of His love (1 John 4:9). It is used of men. As epistles manifesting the character and spirit of Christ (2 Corinthians 3:3; 2 Corinthians 5:11). In the judgment (2 Corinthians 5:10). In all these cases the appearing is not merely an appeal to sense, but is addressed to spiritual perception, and contemplates a moral and spiritual effect. It is the setting forth of the law or will or character of God; of the person or work of Christ; of the character or deeds of men, with a view to the disclosure of their quality and to the producing of a moral impression. Rev., manifested. [source]
John 17:24 I will [τελω]
Perfect identity of his will with that of the Father in “this moment of spiritual exaltation” (Bernard), though in Gethsemane Jesus distinguishes between his human will and that of the Father (Mark 14:36). Where I am That is heaven, to be with Jesus (John 12:26; John 13:36; John 14:3; Romans 8:17; 2 Timothy 2:11.). That they may behold Another purpose clause with ινα — hina and the present active subjunctive of τεωρεω — theōreō “that they may keep on beholding,” the endless joy of seeing Jesus “as he is” (1 John 3:2) in heaven. Before the foundation of the world This same phrase in Ephesians 1:4; 1 Peter 1:20 and six other times we have καταβολη κοσμου — katabolē kosmou (Matthew 25:34; Luke 11:50; Hebrews 4:3; Hebrews 9:26; Revelation 13:8; Revelation 17:8). Here we find the same pre-incarnate consciousness of Christ seen in John 17:5. [source]
John 21:1 Manifested himself [επανεροσεν εαυτον]
First aorist active indicative of πανεροω — phaneroō with the reflexive pronoun (cf. John 7:4; John 13:4). For the passive see John 1:31; John 21:14. Jesus was only seen during the forty days now and then (Acts 1:3), ten instances being recorded. The word πανεροω — phaneroō is often used of Christ on earth (John 1:31; John 2:11; 1 Peter 1:20; 1 John 1:2), of his works (John 3:5), of the second coming (1 John 2:28), of Christ in glory (Colossians 3:4; 1 John 3:2). At By or upon. Of Tiberias As in John 6:1 instead of the usual “Sea of Galilee.” Tiberias, the capital city of Galilee, gave this epithet to the Sea of Galilee. This is not the appearance in Galilee prearranged by Jesus (Mark 16:7; Matthew 28:7, Matthew 28:16). [source]
Acts 3:20 And that he may send the Christ who hath been appointed for you, even Jesus [και αποστειληι τον προκεχειρισμενον υμιν Χριστον Ιησουν]
First aorist active subjunctive with οπως αν — hopōs an as in Acts 15:17 and Luke 2:35. There is little real difference in idea between οπως αν — hopōs an and ινα αν — hina an There is a conditional element in all purpose clauses. The reference is naturally to the second coming of Christ as Acts 3:21 shows. Knowling admits “that there is a spiritual presence of the enthroned Jesus which believers enjoy as a foretaste of the visible and glorious Presence of the Παρουσια — Parousia Jesus did promise to be with the disciples all the days (Matthew 28:20), and certainly repentance with accompanying seasons of refreshing help get the world ready for the coming of the King. The word προκεχειρισμενον — prokecheirisōmenon (perfect passive participle of προχειριζω — procheirizō from προχειρος — procheiros at hand, to take into one‘s hands, to choose) is the correct text here, not προκεκηρυγμενον — prokekērugmenon In the N.T. only here and Acts 22:14; Acts 26:16. It is not “Jesus Christ” here nor “Christ Jesus,” but “the Messiah, Jesus,” identifying Jesus with the Messiah. See the Second Epiphany of Jesus foretold also in 1 Timothy 6:15 and the First Epiphany described in 1 Peter 1:20. [source]
Ephesians 1:4 Before the foundation of the world [προ καταβολης κοσμου]
Old word from καταβαλλω — kataballō to fling down, used of the deposit of seed, the laying of a foundation. This very phrase with προ — pro in the Prayer of Jesus (John 17:24) of love of the Father toward the Son. It occurs also in 1 Peter 1:20. Elsewhere we have απο — apo (from) used with it (Matthew 25:34; Luke 11:50; Hebrews 4:3; Hebrews 9:26; Revelation 13:8; Revelation 17:8). But Paul uses neither phrase elsewhere, though he has απο των αιωνων — apo tōn aiōnōn (from the ages) in Ephesians 3:9. Here in Ephesians 1:3-14. Paul in summary fashion gives an outline of his view of God‘s redemptive plans for the race. That we should be (ειναι ημας — einai hēmās). Infinitive of purpose with the accusative of general reference (ημας — hēmās). See note on Colossians 1:22 for the same two adjectives and also κατενωπιον αυτου — katenōpion autou f0). [source]
1 Timothy 3:16 Was manifest [ἐφανερώθη]
More correctly, was manifested. The verb is used John 1:2; Hebrews 9:26; 1 Peter 1:20; 1 John 3:5, 1 John 3:8, of the historical manifestation of Christ; and of the future coming of Christ in Colossians 3:4; 1 Peter 5:4; 1 John 3:2. [source]
2 Timothy 3:1 In the last days [ἐπ ' ἐσχάταις ἡμέραις]
The phrase only here in Pastorals, Acts 2:17, James 5:3. Similar expressions are ἐν καιρῷ ἐσχάτῳ inthe last season, 1 Peter 1:5: ἐπ ' ἐσχάτου τῶν χρόνων atthe last of the times, 1 Peter 1:20: ἐπ ' ἐσχάτου χρόνου atthe last time, Judges 1:18: ἐπ ' ἐσχάτων τῶν ἡμερῶν atthe last of the days, 2 Peter 3:3: ἐν ὑστέροις καιροῖς inthe latter seasons, 1 Timothy 4:1. The times immediately preceding Christ's second appearing are meant. Comp. Hebrews 1:2; James 5:3. [source]
2 Timothy 1:9 Before the world began [πρὸ χρόνων αἰωνίων]
See additional note on 2 Thessalonians 1:9. In Pastorals the phrase only here and Titus 1:2. Not in Paul. Lit. before eternal times. If it is insisted that αἰώνιος meanseverlasting, this statement is absurd. It is impossible that anything should take place before everlasting times. That would be to say that there was a beginning of times which are from everlasting. Paul puts the beginnings of salvation in God's purpose before the time of the world (1 Corinthians 2:7; 1 Peter 1:20); and Christ's participation in the saving counsels of God prior to time, goes with the Pauline doctrine of Christ's preexistence. The meaning, therefore, of this phrase is rightly given in A.V.: before the world began, that is, before time was reckoned by aeons or cycles. Then, in that timeless present, grace was given to us in God's decree, not actually, since we did not exist. The gift planned and ordered in the eternal counsels is here treated as an actual bestowment. [source]
Hebrews 9:26 Since the foundation of the world [ἀπὸ καταβολῆς κόσμου]
For, from the foundation of the world, sin required atonement by sacrifice; and, therefore, if Christ had been a victim like others, which must be offered repeatedly, he would have had to suffer repeatedly from the foundation of the world. If his sacrifice, like the animal atonements, had availed for a time only, he would have been obliged to repeat his offering whenever that time expired; and, since his atonement was designed to be universal, it would have been necessary for him to appear repeatedly upon earth, and to die repeatedly from the foundation of the world. Comp. 1 Peter 1:20; Revelation 13:8. [source]
Hebrews 1:2 In these last times [ἐπ ' ἐσχάτου τῶν ἡμερῶν τούτων]
Lit. at the last of these days. The exact phrase only here; but comp 1 Peter 1:20and Judges 1:18. lxx, ἐπ ' ἐσχάτου τῶν ἡμερῶν atthe last of the days, Numbers 24:14; Deuteronomy 4:30; Jeremiah 23:20; Jeremiah 25:18; Daniel 10:14. The writer conceives the history of the world in its relation to divine revelation as falling into two great periods. The first he calls αἱ ἡμέραι αὗται thesedays (Hebrews 1:2), and ὀ καιρὸς ὁ ἐνεστηκώς thepresent season (Hebrews 9:9). The second he describes as καιρὸς διορθώσεως theseason of reformation (Hebrews 9:10), which is ὀ καιρὸς ὁ μέλλων theseason to come: comp. ἡ οἰκουμένη ἡ μέλλουσα theworld to come (Hebrews 2:5); μέλλων αἰών theage to come (Hebrews 6:5); πόλις ἡ μέλλουσα thecity to come (Hebrews 12:14). The first period is the period of the old covenant; the second that of the new covenant. The second period does not begin with Christ's first appearing. His appearing and public ministry are at the end of the first period but still within it. The dividing-point between the two periods is the συντέλεια τοῦ αἰῶνος theconsummation of the age, mentioned in Hebrews 9:26. This does not mean the same thing as at the last of these days (Hebrews 1:2), which is the end of the first period denoted by these days, but the conclusion of the first and the beginning of the second period, at which Christ appeared to put away sin by the sacrifice of himself. This is the end of the καιρὸς ἐνεστηκώς thepresent season: this is the limit of the validity of the old sacrificial offerings: this is the inauguration of the time of reformation. The phrase ἐπ ' ἐσχάτου τῶν ἡμερῶν τούτων therefore signifies, in the last days of the first period, when Christ was speaking on earth, and before his crucifixion, which marked the beginning of the second period, the better age of the new covenant. [source]
Hebrews 9:26 Else must he often have suffered [επει εδει αυτον πολλακις πατειν]
A common elliptical use of επει — epei after which one must supply “if that were true” or “in that case,” a protasis of a condition of the second class assumed to be untrue. The conclusion with εδει — edei is without αν — an (verbs of necessity, obligation, etc.). See Robertson, Grammar, p. 963. The conclusion with αν — an occurs in Hebrews 10:2. See also 1 Corinthians 5:10. “Since, if that were true, it would be necessary for him to suffer often.” Since the foundation of the world See Hebrews 4:3 for this phrase. The one sacrifice of Christ is of absolute and final value (1 Peter 1:19.; Revelation 13:8). At the end Consummation or completion as in Matthew 13:39. which see. Hath he been manifested Perfect passive indicative of πανεροω — phaneroō permanent state. See “the primitive hymn or confession of faith” (Moffatt) in 1 Timothy 3:16 and also 1 Peter 1:20. Jesus came once for all (Hebrews 1:2). To put away sin See Hebrews 7:18 for the word ατετησις — athetēsis “The sacrifice of Christ dealt with sin as a principle: the Levitical sacrifices with individual transgressions” (Vincent). [source]
1 Peter 1:2 The foreknowledge [προγνωσιν]
Late substantive (Plutarch, Lucian, papyri) from προγινωσκω — proginōskō (1 Peter 1:20), to know beforehand, only twice in N.T. (here and Acts 2:23 in Peter‘s sermon). In this Epistle Peter often uses substantives rather than verbs (cf. Romans 8:29).Of God the Father (τεου πατρος — theou patros). Anarthous again and genitive case. See πατηρ — patēr applied to God also in 1 Peter 1:3, 1 Peter 1:17 as often by Paul (Romans 1:7, etc.). Peter here presents the Trinity (God the Father, the Spirit, Jesus Christ).In sanctification of the Spirit Clearly the Holy Spirit, though anarthrous like τεου πατρος — theou patros Late word from αγιαζω — hagiazō to render holy Obedience (from υπακουω — hupakouō to hear under, to hearken) to the Lord Jesus as in 1 Peter 1:22 “to the truth,” result of “the sanctification.”And sprinkling of the blood of Jesus Christ Late substantive from ραντιζω — rantizō to sprinkle (Hebrews 9:13), a word used in the lxx of the sacrifices (Num 19:9, 13, 20, etc.), but not in any non-biblical source so far as known, in N.T. only here and Hebrews 12:24 (of the sprinkling of blood). Reference to the death of Christ on the Cross and to the ratification of the New Covenant by the blood of Christ as given in Hebrews 9:19.; Hebrews 12:24 with allusion to Exodus 24:3-8. Paul does not mention this ritual use of the blood of Christ, but Jesus does (Matthew 26:28; Mark 14:24). Hence it is not surprising to find the use of it by Peter and the author of Hebrews. Hort suggests that Peter may also have an ulterior reference to the blood of the martyrs as in Revelation 7:14.; Revelation 12:11, but only as illustration of what Jesus did for us, not as having any value. The whole Epistle is a commentary upon προγνωσις τεου αγιασμος πνευματοσ αιμα Χριστου — prognōsis theouπλητυντειη — hagiasmos pneumatosπλητυνω — haima Christou (Bigg). Peter is not ashamed of the blood of Christ.Be multiplied (πλητυς — plēthuntheiē). First aorist passive optative (volitive) of χαρις και ειρηνη — plēthunō old verb (from ελεος — plēthus fulness), in a wish. So in 2 Peter 1:2; Judges 1:2, but nowhere else in N.T. salutations. Grace and peace (ελεος — charis kai eirēnē) occur together in 2 Peter 1:2, in 2 John 1:2 (with eleos), and in all Paul‘s Epistles (with eleos added in 1 Timothy and 2 Timothy). [source]
2 Peter 3:17 Knowing these things beforehand [προγινωσκοντες]
Present active participle of προγινωσκω — proginōskō as in 1 Peter 1:20. Cf. πρωτον γινωσκω — prōton ginōskō (2 Peter 1:20; 2 Peter 3:1). Hence they are without excuse for misunderstanding Peter or Paul on this subject. [source]
2 Peter 3:3 In the last days [επ εσχατων των ημερων]
“Upon the last of the days.” Judges 1:18 has it επ εσχατου χρονου — ep' eschatou chronou (upon the last time). In 1 Peter 1:5 it is εν καιρωι εσχατωι — en kairōi eschatōi (in the last time), while 1 Peter 1:20 has επ εσχατου των χρονων — ep' eschatou tōn chronōn (upon the last of the times). John has usually τηι εσχατηι ημεραι — tēi eschatēi hēmerāi (on the last day, John 6:39.). Here εσχατων — eschatōn is a predicate adjective like συμμυς μονς — summus mons (the top of the mountain).Mockers with mockery (εμπαιγμονηι εμπαικται — empaigmonēi empaiktai). Note Peter‘s play on words again, both from εμπαιζω — empaizō (Matthew 2:16), to trifle with, and neither found elsewhere save εμπαικτης — empaiktēs in Judges 1:18; Isaiah 3:4 (playing like children). [source]
1 John 2:18 The last hour [ἐσχάτη ὥρα]
The phrase only here in the New Testament. On John's use of ὥρα houras marking a critical season, see John 2:4; John 4:21, John 4:23; John 5:25, John 5:28; John 7:30; John 8:20; John 11:23, John 11:27; John 16:2, John 16:4, John 16:25, John 16:32. The dominant sense of the expression last days, in the New Testament, is that of a period of suffering and struggle preceding a divine victory. See Acts 2:17; James 5:3; 1 Peter 1:20. Hence the phrase here does not refer to the end of the world, but to the period preceding a crisis in the advance of Christ's kingdom, a changeful and troublous period, marked by the appearance of “many antichrists.” [source]
Revelation 13:8 From the foundation of the world []
These words may be construed with slain or with written. In favor of the latter is Revelation 18:8; of the former, 1 Peter 1:19, 1 Peter 1:20. Alford, pertinently as I think, urges the position of the words in favor of the connection with slain, and says that had it not been for the apparent difficulty of the sense thus conveyed, no one would have thought of going so far back as to hath been written for a connection. Render, as Rev., the lamb that hath been slain from the foundation of the world. Καταβολή foundationis literally a throwing or laying down, from καταβάλλω tothrow down; hence a laying down of a foundation. [source]
Revelation 1:1 The Revelation [ἀποκάλυψις]
The Greek word is transcribed in Apocalypse. The word occurs only once in the Gospels, Luke 2:32, where to lighten should be rendered for revelation. It is used there of our Lord, as a light to dispel the darkness under which the heathen were veiled. It occurs thirteen times in Paul's writings, and three times in first Peter. It is used in the following senses: (a.) The unveiling of something hidden, which gives light and knowledge to those who behold it. See Luke 2:32(above). Christianity itself is the revelation of a mystery (Romans 16:25). The participation of the Gentiles in the privileges of the new covenant was made known by revelation (Ephesians 3:3). Paul received the Gospel which he preached by revelation (Galatians 1:12), and went up to Jerusalem by revelation (Galatians 2:2). -DIVIDER-
-DIVIDER-
(b.) Christian insight into spiritual truth. Paul asks for Christians the spirit of revelation (Ephesians 1:17). Peculiar manifestations of the general gift of revelation are given in Christian assemblies (1 Corinthians 14:6, 1 Corinthians 14:26). Special revelations are granted to Paul (2 Corinthians 12:1, 2 Corinthians 12:7). -DIVIDER-
-DIVIDER-
(c.) The second coming of the Lord (1 Peter 1:7, 1 Peter 1:13; 2 Thessalonians 1:7; 1 Corinthians 1:7) in which His glory shall be revealed (1 Peter 4:13), His righteous judgment made known (Romans 2:5), and His children revealed in full majesty (Romans 8:19). -DIVIDER-

-DIVIDER-
The word is compounded with ἀπό fromand καλύπτω tocover. Hence, to remove the cover from anything; to unveil. So of Balaam, the Lord opened or unveiled his eyes ( ἀπεκάλυψεν τοὺς ὀφθαλμοὺς : Numbers 22:31, Sept.). So Boaz to Naomi's kinsman: “I thought to advertise thee:” Rev., “disclose it unto thee” ( ἀποκαλύψω τὸ οὖς σου : Rth 4:4 , Sept.). Lit., I will uncover thine ear. -DIVIDER-
-DIVIDER-
The noun ἀποκάλυψις revelationoccurs only once in the Septuagint (1 Samuel 20:30), in the physical sense of uncovering. The verb is found in the Septuagint in Daniel 2:19, Daniel 2:22, Daniel 2:28. -DIVIDER-
-DIVIDER-
In classical Greek, the verb is used by Herodotus (i., 119) of uncovering the head; and by Plato: thus, “reveal ( ἀποκαλύψας ) to me the power of Rhetoric” (“Gorgias,” 460): “Uncover your chest and back” (“Protagoras,” 352). Both the verb and the noun occur in Plutarch; the latter of uncovering the body, of waters, and of an error. The religious sense, however, is unknown to heathenism. -DIVIDER-
-DIVIDER-
The following words should be compared with this: Ὀπτασία avision (Luke 1:22; Acts 26:19; 2 Corinthians 12:1). Ὅραμα avision (Matthew 17:9; Acts 9:10; Acts 16:9). Ὅρασις avision (Acts 2:17; Revelation 9:17. Of visible form, Revelation 4:3). These three cannot be accurately distinguished. They all denote the thing seen or shown, without anything to show whether it is understood or not. -DIVIDER-

As distinguished from these, ἀποκάλυψις includes, along with the thing shown or seen, its interpretation or unveiling. -DIVIDER-

Ἐπιφάνεια appearing(hence our epiphany ), is used in profane Greek of the appearance of a higher power in order to aid men. In the New Testament by Paul only, and always of the second appearing of Christ in glory, except in 2 Timothy 1:10, where it signifies His first appearing in the flesh. See 2 Thessalonians 2:8; 1 Timothy 6:14; Titus 2:13. As distinguished from this, ἀπολάλυψις is the more comprehensive word. An apocalypse may include several ἐπιφάνειαι appearingsThe appearings are the media of the revealings. -DIVIDER-

Φανέρωσις manifestationonly twice in the New Testament; 1 Corinthians 12:7; 2 Corinthians 4:2. The kindred verb φανερόω tomake manifest, is of frequent occurrence. See on John 21:1. It is not easy, if possible, to show that this word has a less dignified sense than ἀποκάλυψις . The verb φανερόω is used of both the first and the second appearing of our Lord (1 Timothy 3:16; 1 John 1:2; 1 Peter 1:20; Colossians 3:4; 1 Peter 5:4). See also John 2:11; John 21:1. -DIVIDER-

Some distinguish between φανέρωσις as an external manifestation, to the senses, but single and isolated; while ἀποκάλυψις is an inward and abiding disclosure. According to these, the Apocalypse or unveiling, precedes and produces the φανέρωσις or manifestation. The Apocalypse contemplates the thing revealed; the manifestation, the persons to whom it is revealed. -DIVIDER-

The Revelation here is the unveiling of the divine mysteries.Of Jesus ChristNot the manifestation or disclosure of Jesus Christ, but the revelation given by Him.To shew ( δεῖξαι )Frequent in Revelation (Revelation 4:1; Revelation 17:1; Revelation 21:9; Revelation 22:1). Construe with ἔδωκεν gavegave him to shew. Compare “I will give him to sit” (Revelation 3:21): “It was given to hurt” (Revelation 7:2): “It was given him to do;” (A.V. “had power to do;” Revelation 13:14).Servants ( δούλοις )Properly, bond-servants. See on Matthew 20:26; see on Mark 9:35.Must ( δεῖ )As the decree of the absolute and infallible God.Shortly come to pass ( γενέσθαι ἐν τάχει )For the phrase ἐν τάχει shortlysee Luke 18:8, where yet long delay is implied. Expressions like this must be understood, not according to human measurement of time, but rather as in 2 Peter 3:8. The idea is, before long, as time is computed by God. The aorist infinitive γενέσθαι is not begin to come to pass, but denotes a complete fulfilment: must shortly come to pass in their entirety. He sent ( ἀποστείλας )See on Matthew 10:2, Matthew 10:16.Signified ( ἐσήμανεν )From σῆμα asign. Hence, literally, give a sign or token. The verb occurs outside of John's writings only in Acts 11:28; Acts 25:27. See John 12:33; John 18:32; John 21:19. This is its only occurrence in Revelation. The word is appropriate to the symbolic character of the revelation, and so in John 12:33, where Christ predicts the mode of His death in a figure. Compare sign, Revelation 12:1.Angel ( ἀγγέλου )Strictly, a messenger. See Matthew 11:10; Luke 8:24; Luke 9:52. Compare the mediating angel in the visions of Daniel and Zechariah (Daniel 8:15, Daniel 8:16; Daniel 9:21; Daniel 10:10; Zechariah 1:19). See on John 1:51.ServantDesignating the prophetic office. See Isaiah 59:5; Amos 3:7; compare Revelation 19:10; Revelation 22:9.JohnJohn does not name himself in the Gospel or in the Epistles. Here “we are dealing with prophecy, and prophecy requires the guarantee of the individual who is inspired to utter it” (Milligan). Compare Daniel 8:1; Daniel 9:2. [source]

Revelation 13:8 Whose [ουαυτου]
Redundant use of genitive ου — autou (his) with ων — hou (whose) as common in this book, and singular instead of plural παντες — hōn with antecedent ου γεγραπται — pantes (all, plural), thus calling attention to the responsibility of the individual in emperor-worship.Hath not been written (γραπω — ou gegraptai). Perfect passive indicative of εν τωι βιβλιωι της ζωης του αρνιου — graphō permanent state, stands written.In the book of life of the Lamb See Revelation 3:5 for this phrase and the O.T. references. It occurs again in Revelation 17:8; Revelation 20:12, Revelation 20:15; Revelation 21:27. “Here and in Revelation 21:27, the Divine Register is represented as belonging to ‹the Lamb that was slain‘” (Swete).That hath been slain from the foundation of the world (απο καταβολης κοσμου — tou esphagmenou (for which see Revelation 5:6) απο καταβολης κοσμου — apo katabolēs kosmou). For the phrase κοσμου — apo katabolēs kosmou (not in the lxx) there are six other N.T. uses (Matthew 13:35 without προ καταβολης κοσμου — kosmou Matthew 25:34; Luke 11:50; Hebrews 4:3; Hebrews 9:26; Revelation 17:8), and for του εσπαγμενου — pro katabolēs kosmou three (John 17:24; Ephesians 1:4; 1 Peter 1:20). It is doubtful here whether it is to be taken with γεγραπται — tou esphagmenou (cf. 1 Peter 1:20) or with εσπαγμενου — gegraptai as in Revelation 17:8. Either makes sense, and here the most natural use is with esphagmenou At any rate the death of Christ lies in the purpose of God, as in John 3:16. [source]
