Leviticus 1:9-11

New Revised Standard Version Catholic Edition

⁹ but its entrails and its legs shall be washed with water. Then the priest shall turn the whole into smoke on the altar as a burnt offering, an offering by fire of pleasing odor to the Lord.

¹⁰ If your gift for a burnt offering is from the flock, from the sheep or goats, your offering shall be a male without blemish. ¹¹ It shall be slaughtered on the north side of the altar before the Lord, and Aaron’s sons the priests shall dash its blood against all sides of the altar.
