Leviticus 8:14-16

Complete Jewish Bible

(v) ¹⁴ Then the young bull for the sin offering was brought, and Aharon and his sons laid their hands on the head of the bull for the sin offering. ¹⁵ After it had been slaughtered, Moshe took the blood and put it on the horns of the altar all the way around with his finger, thus purifying the altar. The remaining blood he poured out at the base of the altar and consecrated it, to make atonement for it. ¹⁶ Moshe took all the fat on the inner organs, the covering of the liver, the two kidneys and their fat, and made it go up in smoke on the altar.
