Leviticus 22
22 Ref Anything blind or broken or damaged or having any disease or any mark on it may not be offered to the Lord; you may not make an offering of it by fire on the altar to the Lord.
23 Ref An ox or a lamb which has more or less than its natural parts, may be given as a free offering; but it will not be taken in payment of an oath.
24 Ref An animal which has its sex parts damaged or crushed or broken or cut, may not be offered to the Lord; such a thing may not be done anywhere in your land.
