Exodus 29:15-18

15“You shall also take one ram, and Aaron and his sons shall put their hands on the head of the ram;

16and you shall kill the ram, and you shall take its blood and sprinkle it all around on the altar.

17Then you shall cut the ram in pieces, wash its entrails and its legs, and put them with its pieces and with its head.

18And you shall burn the whole ram on the altar. It is a burnt offering to the Lord; it is a sweet aroma, an offering made by fire to the Lord.
