Isaiah 1:11-17

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 fed beasts; I do not delight in the blood of bulls, or of lambs, or of goats.
12 When you come to appear before me, a who asked this from your hand? Trample my courts no more;
13 bringing offerings is futile; incense is an abomination to me. New moon and sabbath and calling of convocation— I cannot endure solemn assemblies with iniquity.
14 Your new moons and your appointed festivals my soul hates; they have become a burden to me, I am weary of bearing them.
15 When you stretch 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.
16 Wash yourselves; make yourselves clean; remove the evil of your doings from before my eyes; cease to do evil,
17 learn to do good; seek justice, rescue the oppressed, defend the orphan, plead for the widow.
