Leviticus 8:14-16

New Century Version

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, took the blood, and with his finger put some of it on all the corners of the altar, to make it pure. Then he poured out the rest of the blood at the bottom of the altar. In this way he made it holy and ready for service to God. ¹⁶ Moses took all the fat from the inner organs of the bull, the best part of the liver, and both kidneys with the fat that is on them, and he burned them on the altar.
