26 Help me, O Lord my God! Oh, save me according to Your mercy, 27 That they may know that this is Your hand— That You, Lord, have done it! (Psalm 109:26–27, NKJV)
David had enemies who terrorized him and wanted him dead. King Saul was chief among this number (1 Sam. 18:25, 28; 19:1; 20:30-33). Psalm 109 is David’s plea to the Lord to hold his enemies accountable for their sins against him. They had spoken deceit and lies against David (109:2). Hatred consumed them, driving them to fight against him unjustly (109:3). They had rewarded his love and prayers with hateful accusations and threats (109:4-5). David’s prayer calls for divine retribution against these evildoers (109:6-20). Without context, it sounds harsh. In truth, it is his earnest supplication for God to bring judgment upon them for their evil works. God’s judgments are according to truth. They are righteous and applied impartially according to our conduct (Rom. 2:1-11). David did not repay their evil with revenge. He left the matter in God’s hands, who saved him from trouble (2 Sam. 24:6-7, 9-12). David was confident God in mercy would save him (Psa. 138:7). David was sure his enemies would be able to see God’s power at work in the deliverance he would receive from God’s hand. God worked to deliver David in answer to his prayers. God still works in our lives to answer prayers when we depend on His presence, power, mercy, and deliverance (1 Jno. 3:21-22; 5:14-15).
