Leviticus 8
18 Ref 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 Ref And when the sheep had been cut into parts, the head and the parts and the fat were burned by Moses.
21 Ref 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.
