Even though Achan"s sin carried a punishment that he could not decrease or postpone, Achan could at least reduce his guilt by confessing his sin. This he did in response to Joshua"s paternal entreaty ( Joshua 7:19). Confessing one"s sin is one way to glorify God. [source][source][source]
Achan"s confession clearly revealed the process involved in yielding to temptation ( Joshua 7:21). He allowed the sight of something attractive to grow into covetousness. Then he took the step from covert mental sin to overt physical sin. Finally he sought to cover his action rather than confessing it. The same progression appears in the story of the Fall and in the story of David"s sin with Bathsheba ( Genesis 3:6-7; Genesis 3:10; 2 Samuel 11:2-4; 2 Samuel 11:8). One shekel weighed about four ounces. Josephus wrote that the mantle from Shinar that Achan took was "a royal garment woven entirely of gold." [1][source]
The Israelites punished Achan"s children with him ( Joshua 7:24), evidently because they had participated in his sin (cf. Proverbs 15:27). [2] It would have been difficult for Achan to hide the amount of spoil he took under his tent without his family"s knowledge. The people also destroyed all of Achan"s possessions (cf. Deuteronomy 13:16-17). Achan"s sin was high-handed defiance against God (cf. Numbers 15:30; Numbers 15:35). [source][source][source]
The heap of stones the people raised over Achan, his family, and his possessions ( Joshua 7:26) memorialized this act of rebellion for the Israelites and their children (cf. Joshua 8:29; 2 Samuel 18:17). They named the valley in which the execution took place "Achor" (lit. troubling or disaster) as a further reminder (cf. Hosea 2:15; Isaiah 65:10). Note the wordplay with Achan"s name. [source][source][source]
"Whilst they [3] learned from his mercies how greatly he was to be loved, they needed also to learn from his judgments how greatly he was to be feared." [4][source]
Israel"s defeat at Ai graphically illustrates the far-reaching influence of sin. The private sin of one or a few individuals can affect the welfare of many other people who do not personally commit that sin. [source][source][source]
Achan and his family were to Israel at this time what Ananias and Sapphira were to the early church ( Acts 5). They were a strong warning of the consequences of sin among God"s people. Nadab and Abihu ( Leviticus 10), and Korah and his cohorts ( Numbers 16), were similar examples. The fact that God does not judge sin today as He did on these occasions does not mean He feels any less strongly about it. He mercifully withholds judgment in most instances. Nevertheless sin still produces the same destruction and death. [source][source][source]
"God"s first revenges are so much more fearful, because they must be exemplary." [5][source]
God"s punishment on Achan was not unfair. It is only by God"s mercy that any sinner lives to old age. God can judge any sinner at any time in his or her life and be perfectly just. No sinner has any claim on God"s grace. God is no man"s debtor. [source][source][source]
"As we read in ch. vii the story of Israel"s first fight and first failure, we shall see that there were in the main, two causes of defeat: self-confidence, and covetousness; and these are still prime causes of failure in a Christian life." [6][source]
Chapters1-7 form a unit of text: the Jericho siege narrative. Rahab and Achan open and close this section respectively forming its "bookends." Rahab was a female Canaanite prostitute; Achan was an Israelite man. Rahab hid the spies under her roof; Achan hid stolen loot under his tent. Rahab, her house, and her family were saved; Achan, his tent, and his family were destroyed. The writer was teaching theology by the way he constructed his narrative. [7][source]
