Leviticus 22:23

You may present a bull or a lamb that has a part too long or too short for a freewill offering , but for a vow offering it cannot be accepted .

You may, however, present as a freewill offering an ox or a sheep that is deformed or stunted, but it will not be accepted in fulfillment of a vow.

Either a bullock or a lamb that hath any thing superfluous or lacking in his parts, that mayest thou offer for a freewill offering; but for a vow it shall not be accepted.
