Leviticus 22:21

22:21 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.

Leviticus 22:23

22:23 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.
