109:1ff David endured many false accusations (1 Samuel 22:7-13; 2 Samuel 15:3, 4), as did Christ centuries later (Matthew 26:59-61; 27:39-44). Verse 8 is quoted in Acts 1:20 as being fulfilled in Judas’s death.
109:4 David was angry at being attacked by evil people who slandered him and lied. Yet David remained a friend and a man of prayer. While we must hate evil and work to overcome it, we must love everyone, including those who do evil, because God loves them. We are called to hate the sin, but love the person. Only through God’s strength will we be able to follow David’s example.
109:6-20 This is another of the imprecatory psalms, a call for God to judge the wicked. (For an explanation of imprecatory psalms, see the note on 35:1ff.) David was not taking vengeance into his own hands; he was asking that God be swift in his promised judgment of evil people. David’s words depict the eventual doom of all God’s enemies.
