Isaiah 1:15-17

15And when ye spread forth your hands, I will hide my eyes from you: yea, when ye make many prayers, I will not hear: your hands are full of blood.12

16Wash yourselves, make yourselves clean; put away the evil of your doings from before my eyes; cease to do evil; 17Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow.3
