'Perverse' in the Bible

With the pure Thou showest Thyself pure, And with the perverse showest Thyself a wrestler,

They search out perverse things, 'We perfected a searching search,' And the inward part of man, and the heart are deep.

O my God, cause me to escape From the hand of the wicked, From the hand of the perverse and violent.

A perverse heart turneth aside from me, Wickedness I know not.
