Leviticus 22:21-23

²¹And 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.

²²Anything 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.

²³An 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.
