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. When you come to appear before me, who asked this from your hand? Trample my courts no more; 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. Your new moons and your appointed festivals my soul hates; they have become a burden to me, I am weary of bearing them. 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. Wash yourselves; make yourselves clean; remove the evil of your doings from before my eyes; cease to do evil, learn to do good; seek justice, rescue the oppressed, defend the orphan, plead for the widow. -- Isaiah 1:11-17

For in the day that I brought your ancestors out of the land of Egypt, I did not speak to them or command them concerning burnt offerings and sacrifices. But this command I gave them, "Obey my voice, and I will be your God, and you shall be my people; and walk only in the way that I command you, so that it may be well with you." -- Jer. 7:22-23

For I desire steadfast love and not sacrifice, the knowledge of God rather than burnt offerings. -- Hosea 6:6

I hate, I despise your festivals, and I take no delight in your solemn assemblies. Even though you offer me your burnt offerings and grain offerings, I will not accept them; and the offerings of well-being of your fatted animals I will not look upon. Take away from me the noise of your songs; I will not listen to the melody of your harps. But let justice roll down like waters, and righteousness like an ever-flowing stream. -- Amos 5:21-24

Hear what the LORD says: Rise, plead your case before the mountains, and let the hills hear your voice. Hear, you mountains, the controversy of the LORD, and you enduring foundations of the earth; for the LORD has a controversy with his people, and he will contend with Israel. "O my people, what have I done to you? In what have I wearied you? Answer me! For I brought you up from the land of Egypt, and redeemed you from the house of slavery; and I sent before you Moses, Aaron, and Miriam. "With what shall I come before the LORD, and bow myself before God on high? Shall I come before him with burnt offerings, with calves a year old? Will the LORD be pleased with thousands of rams, with ten thousands of rivers of oil? Shall I give my firstborn for my transgression, the fruit of my body for the sin of my soul?" He has told you, O mortal, what is good; and what does the LORD require of you but to do justice, and to love kindness, and to walk humbly with your God? -- Micah 6:1-4, 6-8

[Jesus said,] "Go and learn what this means, 'I desire mercy, not sacrifice.' For I have come to call not the righteous but sinners." -- Matthew 9:13

[Jesus said,] "But if you had known what this means, 'I desire mercy and not sacrifice,' you would not have condemned the guiltless." -- Matthew 12:7
