And when you stretch forth your hands, I will turn away my eyes from you; and when you multiply prayer, I will not hear: for your hands are full of blood. Wash yourselves, be clean take away the evil of your devices from my eyes: cease to do perversely. Learn to do well: seek judgment, relieve the oppressed, judge for the fatherless, defend the widow.

– Isaias, 1: 15-17
