What does Psalm 4:5 mean?

David continues his appeal to his followers (Psalm 4:4) by exhorting them to properly honor God. Of course, David's followers could not offer sacrifices to the Lord when they were in the wilderness (2 Samuel 15:13–14), but they could do so upon returning to Jerusalem in victory. The tabernacle in Jerusalem was the site where worshipers offered sacrifices to the Lord. Absalom offered sacrifices, but he did so as a hypocrite (2 Samuel 15:12). At the time, he was conspiring to overthrow King David.

God only accepts worship that is offered to Him "in spirit and truth" (John 4:24). Although believers today do not offer animal sacrifices, we can offer the sacrifice of our submission: placing our bodies under His authority and control (Romans 12:1), the sacrifice of generous giving (Philippians 4:18), and the sacrifice of praise (Hebrews 13:15). David encourages his men to place their confidence in the Lord. They were outnumbered by their foes (Psalm 3:1), but the Lord is all powerful, and He rewards those who trust in Him (Hebrews 11:6).
