Leviticus 8:14-16

Living Bible

¹⁴ Then he took the young bull for the sin offering, and Aaron and his sons laid their hands upon its head ^15-16 as Moses killed it. He smeared some of the blood with his finger upon the four horns of the altar and upon the altar itself, to sanctify it, and poured out the rest of the blood at the base of the altar; thus he sanctified the altar, making atonement for it. He took all the fat covering the entrails, the fatty mass above the liver, and the two kidneys and their fat, and burned them all on the altar.
