Bible Verses About Sacrifices: Unaccepted in, on account of sin

What unto me is the multitude of your sacrifices? saith Jehovah: I have had enough of the burnt-offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he-goats.

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

He that killeth an ox is as he that slayeth a man; he that sacrificeth a lamb, as he that breaketh a dog’s neck; he that offereth an oblation, as he that offereth swine’s blood; he that burneth frankincense, as he that blesseth an idol. Yea, they have chosen their own ways, and their soul delighteth in their abominations:

As for the sacrifices of mine offerings, they sacrifice flesh and eat it; but Jehovah accepteth them not: now will he remember their iniquity, and visit their sins; they shall return to Egypt.
