Leviticus 8:13-16

¹³And Moses brought Aaron's sons, and clothed them with tunics, and girded them with girdles, and bound head-tires upon them; as the LORD commanded Moses.

¹⁴And the bullock of the sin-offering was brought; and Aaron and his sons laid their hands upon the head of the bullock of the sin-offering.

¹⁵And when it was slain, Moses took the blood, and put it upon the horns of the altar round about with his finger, and purified the altar, and poured out the remaining blood at the base of the altar, and sanctified it, to make atonement for it.

¹⁶And he took all the fat that was upon the inwards, and the lobe of the liver, and the two kidneys, and their fat, and Moses made it smoke upon the altar.
