David begins with a direct question: do you indeed decree what is right, you mighty ones? Do you judge the children of man uprightly? No: in your hearts you devise wrongs, and your hands deal out violence on earth. It is an accusation against those who hold authority and use it for evil.
Then he describes wickedness from its origin: the wicked are estranged from the womb; they go astray from birth, speaking lies. They have venom like the venom of a serpent, like the deaf adder that stops its ear, so as not to hear the voice of charmers or of the cunning enchanter. The picture shows that there is no one who can bring them to reason.
Then David prays with force: O God, break the teeth in their mouths; tear out the fangs of the young lions, O Lord! Let them vanish like water that runs away, let their arrows be blunted, let them be like a snail that dissolves into slime, like the stillborn child who never sees the sun. The righteous will rejoice when he sees the vengeance and will bathe his feet in the blood of the wicked. Then mankind will say: surely there is a reward for the righteous; surely there is a God who judges on earth.
