Exodus 29:19

15 Take one of the rams, and Aaron and his sons shall lay their hands on its head.

16 You are to slaughter the ram, take its blood, and sprinkle it on all sides of the altar.

17 Cut the ram into pieces, wash the entrails and legs, and place them with its head and other pieces.

18 Then burn the entire ram on the altar; it is a burnt offering to the LORD, a pleasing aroma, an offering made by fire to the LORD.

19 Take the second ram, and Aaron and his sons are to lay their hands on its head.

20 Slaughter the ram, take some of its blood, and put it on the right earlobes of Aaron and his sons, on the thumbs of their right hands, and on the big toes of their right feet. Sprinkle the remaining blood on all sides of the altar.

21 And take some of the blood on the altar and some of the anointing oil and sprinkle it on Aaron and his garments, as well as on his sons and their garments. Then he and his garments will be consecrated, as well as his sons and their garments.

22 Take the fat from the ram, the fat tail, the fat covering the entrails, the lobe of the liver, both kidneys with the fat on them, and the right thigh (since this is a ram for ordination),

23 along with one loaf of bread, one cake of bread made with oil, and one wafer from the basket of unleavened bread that is before the LORD.
