Exodus 29:18

18 and turn the whole ram into smoke on the altar; it is a burnt offering to the Lord; it is a pleasing odor, an offering by fire to the Lord.

Exodus 29:18 In-Context

16 and you shall slaughter the ram, and shall take its blood and dash it against all sides of the altar.
17 Then you shall cut the ram into its parts, and wash its entrails and its legs, and put them with its parts and its head,
18 and turn the whole ram into smoke on the altar; it is a burnt offering to the Lord; it is a pleasing odor, an offering by fire to the Lord.
19 You shall take the other ram; and Aaron and his sons shall lay their hands on the head of the ram,
20 and you shall slaughter the ram, and take some of its blood and put it on the lobe of Aaron's right ear and on the lobes of the right ears of his sons, and on the thumbs of their right hands, and on the big toes of their right feet, and dash the rest of the blood against all sides of the altar.
