To the choirmaster: according to Do Not Destroy. A Miktam of David.

¹Do you indeed decree what is right, you gods? Do you judge the children of man uprightly?

²No, in your hearts you devise wrongs; your hands deal out violence on earth.

³The wicked are estranged from the womb; they go astray from birth, speaking lies.

⁴They have venom like the venom of a serpent, like the deaf adder that stops its ear,

⁵so that it does not hear the voice of charmers or of the cunning enchanter.

⁶O God, break the teeth in their mouths; tear out the fangs of the young lions, O LORD!

⁷Let them vanish like water that runs away; when he aims his arrows, let them be blunted.

⁸Let them be like the snail that dissolves into slime, like the stillborn child who never sees the sun.

⁹Sooner than your pots can feel the heat of thorns, whether green or ablaze, may he sweep them away!

¹⁰The righteous will rejoice when he sees the vengeance; he will bathe his feet in the blood of the wicked.

¹¹Mankind will say, “Surely there is a reward for the righteous; surely there is a God who judges on earth.”
