Leviticus 22:20-22

Whatever has a defect, you shall not offer, for it will not be accepted for you. When someone offers a sacrifice of peace offerings to the LORD to fulfill a special vow or for a voluntary offering, of the herd or of the flock, it must be without defect to be accepted; there shall be no defect in it. Those 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.
