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

1   Do you indeed decree what is right, you gods?
    Do you judge the children of man uprightly?
2   No, in your hearts you devise wrongs;
    your hands deal out violence on earth.
3   The wicked are estranged from the womb;
    they go astray from birth, speaking lies.
4   They have venom like the venom of a serpent,
    like the deaf adder that stops its ear,
5   so that it does not hear the voice of charmers
    or of the cunning enchanter.
6   O God, break the teeth in their mouths;
    tear out the fangs of the young lions, O LORD!
7   Let them vanish like water that runs away;
    when he aims his arrows, let them be blunted.
8   Let them be like the snail that dissolves into slime,
    like the stillborn child who never sees the sun.
9   Sooner than your pots can feel the heat of thorns,
    whether green or ablaze, may he sweep them away!
10   The righteous will rejoice when he sees the vengeance;
    he will bathe his feet in the blood of the wicked.
11   Mankind will say, “Surely there is a reward for the righteous;
    surely there is a God who judges on earth.”
