David endured many false accusations (1Sa_22:7-13; 2Sa_15:3-4), as did Christ centuries later (Mat_26:59-61; Mat_27:39-44). Verse 8 is quoted in Act 1:20 as being fulfilled in Judas's death.
Psalms 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.
Psalms 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 Psa 35:1 ff.) 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.
