Leviticus 8:20-22

Amplified Bible

²⁰ When he had cut the ram into pieces, Moses offered up the head, the pieces, and the fat in smoke. ²¹ After he had washed the entrails and the legs in water, Moses offered up the whole ram in smoke on the altar. It was a burnt offering for a sweet and soothing aroma, an offering by fire to the Lord, just as the Lord had commanded Moses.

²² Then he brought the second ram, the ram of consecration (ordination), and Aaron and his sons laid their hands on the head of the ram.
