Leviticus 22:20-22

20But whatsoever hath a blemish, that shall ye not offer: for it shall not be acceptable for you. 21And whosoever offereth a sacrifice of peace-offerings unto Jehovah to accomplish a vow, or for a freewill-offering, of the herd or of the flock, it shall be perfect to be accepted; there shall be no blemish therein. 22Blind, or broken, or maimed, or having a wen, or scurvy, or scabbed, ye shall not offer these unto Jehovah, nor make an offering by fire of them upon the altar unto Jehovah.
