Leviticus 8:21

18 And he put the male sheep of the burned offering before the Lord, and Aaron and his sons put their hands on its head,

19 And he put it to death; and Moses put some of the blood on and round the altar.

20 And when the sheep had been cut into parts, the head and the parts and the fat were burned by Moses.

21 And the inside parts and the legs were washed with water and all the sheep was burned by Moses on the altar; it was a burned offering for a sweet smell: it was an offering made by fire to the Lord, as the Lord gave orders to Moses.

22 And he put the other sheep before the Lord, the sheep with which they were made priests; and Aaron and his sons put their hands on the head of the sheep,

23 And he put it to death; and Moses took some of the blood and put it on the point of Aaron's right ear and on the thumb of his right hand and on the great toe of his right foot.

24 Then he took Aaron's sons, and Moses put some of the blood on the point of their right ears and on the thumbs of their right hands and on the great toes of their right feet: and Moses put the blood on and round the altar.
