21When a man presents a peace offering to the LORD from the herd or flock to fulfill a vow or as a freewill offering, it must be without blemish or defect to be acceptable.
22You are not to present to the LORD any animal that is blind, injured, or maimed, or anything with a running sore, a festering rash, or a scab; you must not put any of these on the altar as an offering made by fire to the LORD.
23You may present as a freewill offering an ox or sheep that has a deformed or stunted limb, but it is not acceptable in fulfillment of a vow.
— Leviticus 22:21-23
