Bible Verses About Vows: Clean beasts the subjects of, not to be redeemed

“‘If it is an animal, of which men offer an offering to the LORD, all that any man gives of such to the LORD becomes holy.

He shall not alter it, nor change it, a good for a bad, or a bad for a good: and if he shall at all change animal for animal, then both it and that for which it is changed shall be holy.
