Leviticus 22:21-23

²¹'And when a man bringeth near a sacrifice of peace-offerings to Jehovah, to complete a vow, or for a willing-offering, of the herd or of the flock, it is perfect for a pleasing thing: no blemish is in it;

²²blind, or broken, or maimed, or having a wen, or scurvy, or scabbed — ye do not bring these near to Jehovah, and a fire-offering ye do not make of them on the altar to Jehovah.

²³'As to an ox or a sheep enlarged or dwarfed — a willing-offering ye do make it, but for a vow it is not pleasing.
