What does Psalm 64:10 mean?

By faith, David saw his life experiences as examples from which others could learn. This psalm is not officially tied to any specific moment in his life. However, it expresses David's confidence that those who participate in slander (Psalm 64:2–3), conspiracy (Psalm 64:4), and plotting (Psalm 64:5–6) will instead find themselves exposed and judged by God (Psalm 64:7–9). Enemies plotted to kill David (1 Samuel 19:11; 2 Samuel 15:13–14), but those schemes were defeated and the enemies were made examples for the entire world (Psalm 40:3; 52:6–7; 58:10–11).

David calls on believers in the Lord to express trust and praise in their God (Psalm 62:8; 118:8–9). Psalm 103:4 gives one reason to praise the Lord by saying He "redeems your life from the pit, who crowns you with steadfast love and mercy." Revelation 5 pictures the eternal, permanent fulfillment of God's promise to care for His people. John saw redeemed saints in heaven praising Jesus, the Lamb of God. In his vision, they cried out, "Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation, and you have made them a kingdom and priests to our God, and they shall reign on the earth" (Revelation 5:9–10). Believers today can praise the Lord as well for what He has done, is doing, and will do.
