Leviticus 22:21-23

Revised Standard Version Catholic Edition

²¹ And when any one offers a sacrifice of peace offerings to the Lord, to fulfil a vow or as a freewill offering, from the herd or from the flock, to be accepted it must be perfect; there shall be no blemish in it. ²² Animals blind or disabled or mutilated or having a discharge or an itch or scabs, you shall not offer to the Lord or make of them an offering by fire upon the altar to the Lord. ²³ A bull or a lamb which has a part too long or too short you may present for a freewill offering; but for a votive offering it cannot be accepted.
