Leviticus 22:21-23

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.

²³Either a bullock or a lamb that hath anything superfluous or lacking in his parts, that mayest thou offer for a freewill-offering; but for a vow it shall not be accepted.
