Leviticus 8:18-21

18He brought forward the ram for the burnt offering. Aaron and his sons placed their hands on the ram’s head.

19Moses slaughtered it and threw the blood against the altar on all sides.

20When the ram was cut into pieces, Moses burned the head with the other pieces and the fat.

21He washed the internal organs and the legs. Then Moses burned the whole ram on the altar as the Lord commanded him. It was a burnt offering, a soothing aroma, an offering by fire to the Lord.
