Leviticus 22:20-22

201Whatever has a defect, you shall not offer, for it will not be accepted for you.

21When someone offers a sacrifice of peace offerings to the Lord 2to fulfill a special vow or for a 3voluntary offering, 4of the herd or 5of the flock, it must be without defect to be accepted; there shall be no defect in it.

22Those that are blind, fractured, maimed, or have a wart, a festering rash, or scabs, you shall not offer to the Lord, nor make of them an offering by fire on the altar to the Lord.
