Isaiah 1
15 Ref When you spread forth your hands, I will hide my eyes from you; Yes, when you make many prayers, I will not hear. Your hands are full of blood.
16 Ref Wash yourselves, make yourself clean. Put away the evil of your doings from before my eyes; Cease to do evil.
17 Ref Learn to do well. Seek justice, Relieve the oppressed, Judge the fatherless, Plead for the widow."
