Exodus 29:19

17 And thou shalt cut the ram in pieces, and wash the inwards of him, and his legs, and put them unto his pieces, and unto his head.

18 And thou shalt burn the whole ram upon the altar: it is a burnt offering unto the LORD: it is a sweet savour, an offering made by fire unto the LORD.

19 And thou shalt take the other ram; and Aaron and his sons shall put their hands upon the head of the ram.

20 Then shalt thou kill the ram, and take of his blood, and put it upon the tip of the right ear of Aaron, and upon the tip of the right ear of his sons, and upon the thumb of their right hand, and upon the great toe of their right foot, and sprinkle the blood upon the altar round about.

21 And thou shalt take of the blood that is upon the altar, and of the anointing oil, and sprinkle it upon Aaron, and upon his garments, and upon his sons, and upon the garments of his sons with him: and he shall be hallowed, and his garments, and his sons, and his sons’ garments with him.
