Leviticus 22
21 Ref And whoever makes a peace-offering to the Lord, in payment of an oath or as a free offering, from the herd or the flock, if it is to be pleasing to the Lord, let it be free from any mark or damage.
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.
