Leviticus 8:14-16

New Revised Standard Version Catholic Edition

¹⁴ He led forward the bull of sin offering; and Aaron and his sons laid their hands upon the head of the bull of sin offering, ¹⁵ and it was slaughtered. Moses took the blood and with his finger put some on each of the horns of the altar, purifying the altar; then he poured out the blood at the base of the altar. Thus he consecrated it, to make atonement for it. ¹⁶ Moses took all the fat that was around the entrails, and the appendage of the liver, and the two kidneys with their fat, and turned them into smoke on the altar.
