Leviticus 8:18-21

18Then he presented the burnt offering ram and Aaron and his sons laid their hands on the head of the ram,

19and he slaughtered it. Moses then splashed the blood against the altar’s sides.

20Then he cut the ram into parts, and Moses offered the head, the parts, and the suet up in smoke,

21but the entrails and the legs he washed with water, and Moses offered the whole ram up in smoke on the altar – it was a burnt offering for a soothing aroma, a gift to the Lord, just as the Lord had commanded Moses.
