Leviticus 4:17-19

New Revised Standard Version Catholic Edition

¹⁷ and the priest shall dip his finger in the blood and sprinkle it seven times before the Lord, in front of the curtain. ¹⁸ He shall put some of the blood on the horns of the altar that is before the Lord in the tent of meeting; and the rest of the blood he shall pour out at the base of the altar of burnt offering that is at the entrance of the tent of meeting. ¹⁹ He shall remove all its fat and turn it into smoke on the altar.
