Isaiah 1:11; Isaiah 1:15

11 "What to me is the multitude of your sacrifices? says the LORD; I have had enough of burnt offerings of rams and the fat of well-fed beasts; I do not delight in the blood of bulls, or of lambs, or of goats.

15 When you spread out your hands, I will hide my eyes from you; even though you make many prayers, I will not listen; your hands are full of blood.
