Leviticus 22:19-21

¹⁹So that it may be pleasing to the Lord, let him give a male, without any mark, from among the oxen or the sheep or the goats.

²⁰But anything which has a mark you may not give; it will not make you pleasing to the Lord.

²¹And whoever makes a peace-offering to the Lord, in payment of an oath or as a free offering, from the herd or the flock, if it is to be pleasing to the Lord, let it be free from any mark or damage.
