He could rest and sleep peacefully with this knowledge (cf. Psalm 3:5). Even though many sinners opposed him, he was right with his righteous God. He knew God would protect him. David"s name means "beloved," and his words in this verse express his appreciation for the fact that he was beloved by the Lord. [source][source][source]
The elect of God can experience true joy and peace-even though the ungodly may oppose them-because He will protect and provide for them (cf. Galatians 5:22; Romans 14:17). [source][source][source]
"As an expression of confidence in God, the psalm helps the reader to meditate on God"s fatherly care and to leave the troubles and causes of anxiety in his hands. Here the psalmist teaches us that in our walk with God he can bring us to the point where we can sleep without fear." [1][source]
Context Summary
Psalm 4:1-8 - Morning And Evening Prayers
These psalms probably date from David's flight before Absalom, 2 Samuel 16:1-23. It is the perfection of trust to be able to sleep when our foes are many and set upon our destruction. So Jesus slept, Mark 4:38; and Peter, Acts 12:6. Be sure that you are where God would have you to be, and then resign yourself to His loving care. Even though pursued by the results of your sins, you will find that God will save you, on condition of your being contrite.
Let us begin the day and close it with thanksgivings and prayers. Godly means having the power to love. Dost thou love God and His saints? Then know that He has set thee apart-that is, separated thee-for Himself. Seek His will alone. Be content to let the world go by. Thou hast no need to envy the prosperous worldling. God suffices for heaven; why not for earth? [source]
