The psalm begins with a petition: deliver me, O Lord, from evil men; preserve me from violent men. Verses 2 and 3 describe them: they plan evil things in their hearts, stir up wars continually, sharpen their tongues like serpents, and under their lips is the venom of vipers. The most dangerous wickedness here is not the sword but the word.
Verses 4 and 5 repeat the petition with new images: guard me from the hands of the wicked, from violent men who have planned to trip my feet. The proud have hidden a trap and cords, spread a net and set snares by the wayside.
In verses 6 to 8 David turns to the Lord: I say to the Lord, you are my God; give ear to the voice of my pleas. He calls him the strength of his salvation, who covered his head in the day of battle, and asks that he not grant the desires of the wicked. Verses 9 to 11 ask that the mischief of the lips of his enemies cover them, that burning coals fall on them and that they be cast into pits. Verses 12 and 13 end with certainty: the Lord will maintain the cause of the afflicted and the justice due the needy, and the righteous will give thanks to his name and the upright will dwell in his presence.
