¹⁴ Then Moses brought the bull for the sin offering. And Aaron and his sons put their hands on its head. ¹⁵ Moses killed the bull and took some of the blood. With his finger he put some of the blood on all the corners of the altar. In this way he made the altar pure. Then he poured out the rest of the blood at the bottom of the altar. So he made it holy and ready for service to God. ¹⁶ Moses took all the fat from the inner organs of the bull. He took the best part of the liver. And he took both kidneys and the fat on them. Then he burned them on the altar.
