Leviticus 22:21-23

²¹And whosoever offereth a sacrifice of peace offerings unto the LORD to accomplish his vow, or a freewill offering in beeves or sheep, 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 the LORD, nor make an offering by fire of them upon the altar unto the LORD.

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