Verses 1-31
Psalm 109 Those who afflict others
David complains to God about the unjust attacks of his opponents and the false accusations they bring against him (1-3). He has no desire for personal revenge; rather he has shown love for his enemies and has prayed for them (4-5).
Nevertheless, in the prayer that follows, David uses strong language as he pleads for justice to be done. With the cruelty of his enemies increasing, he hands the case over to God, the righteous judge, who will repay the wicked for their wickedness. In particular David has in mind the leader of his accusers (6-7). (See section 'Curses on the wicked' that follows notes on Psalm 7.) The evildoer will receive fitting justice if he suffers the sorrows he intended to bring upon David. The curses listed here display the character of the aggressor and the evil he intended to do to David and his family (8-15). The man ruthlessly persecuted those who could not defend themselves, and deserves a punishment that is similarly ruthless (16-20).
As for David, he is weak, sick and despised, as helpless as an insect about to be blown away. Only God can save him now (21-25). He wants God to save him and punish his persecutors in such a way that people will see the events as the direct work of God (26-29). True justice is found with God alone. David is therefore confident that God will rescue him (30-31).
