¹⁴ Then Moses brought out the bull of the sin offering. Aaron and his sons put their hands on the bull’s head. ¹⁵ Then Moses killed the bull and collected its blood. He used his finger to put some of the blood on all the corners of the altar. In this way he made the altar ready for sacrifices. Then he poured out the blood at the base of the altar to make the altar ready for sacrifices to make the people pure. ¹⁶ Moses took all the fat from the inner parts of the bull. He took the fat part of the liver with the two kidneys and the fat on them. Then he burned them on the altar.
