Leviticus 22:21-23

If a man presents a peace offering sacrifice to the LORD for a special votive offering or for a freewill offering from the herd or the flock, it must be flawless to be acceptable; it must have no flaw. “‘You must not present to the LORD something blind, or with a broken bone, or mutilated, or with a running sore, or with a festering eruption, or with a feverish rash. You must not give any of these as a gift on the altar to the LORD. As for an ox or a sheep with a limb too long or stunted, you may present it as a freewill offering, but it will not be acceptable for a votive offering.
