Psalms 71:4

Deliver me, O my God, out of the hand of the wicked, out of the hand of the unrighteous and cruel man.

Ver. 4. Out of the hand of the unrighteous] That seeketh by fraud to undermine me, and by force to overturn me.

And cruel man] Qui totus in fermento iacet; sour as leaven, sharp as vinegar.
