Exodus 29:16-18

And thou shalt slay the ram, and thou shalt take its blood, and sprinkle it round about upon the altar.

And thou shalt cut the ram into its pieces, and wash its inwards, and its legs, and put them with its pieces, and with its head.

And thou shalt burn the whole ram upon the altar: it is a burnt-offering unto Jehovah; it is a sweet savor, an offering made by fire unto Jehovah.
