Leviticus 22:18-23

18“Speak to Aaron, his sons, and all the Israelites and tell them, ‘When any man from the house of Israel or from the foreigners in Israel presents his offering for any of the votive or freewill offerings which they present to the Lord as a burnt offering,

19if it is to be acceptable for your benefit it must be a flawless male from the cattle, sheep, or goats.

20You must not present anything that has a flaw, because it will not be acceptable for your benefit.

21If 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.

22“‘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.

23As 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.
