Leviticus 22:19-21

New Revised Standard Version Catholic Edition

¹⁹ to be acceptable in your behalf it shall be a male without blemish, of the cattle or the sheep or the goats. ²⁰ You shall not offer anything that has a blemish, for it will not be acceptable in your behalf.

²¹ When anyone offers a sacrifice of well-being to the Lord, in fulfillment of a vow or as a freewill offering, from the herd or from the flock, to be acceptable it must be perfect; there shall be no blemish in it.
