Leviticus 22:20-22

New Catholic Bible

²⁰ You shall offer nothing with a defect; it shall not be acceptable for you. ²¹ If someone offers a peace offering as the fulfillment of a vow or as a free-will offering, whether it be from the cattle or the sheep, it must be perfect to be acceptable. It must have no defect. ²² You shall not offer anything that is blind or injured or maimed, or anything with sores or scabs or scales. You shall not use these as an offering to the Lord by fire, on the altar to the Lord.
