Leviticus 1:9 (KJV)

And the sons of Aaron the priest shall put fire upon the altar, and lay the wood in order upon the fire:

And the priests, Aaron’s sons, shall lay the parts, the head, and the fat, in order upon the wood that is on the fire which is upon the altar:

But his inwards and his legs shall he wash in water: and the priest shall burn all on the altar, to be a burnt sacrifice, an offering made by fire, of a sweet savour unto the Lord.

And if his offering be of the flocks, namely, of the sheep, or of the goats, for a burnt sacrifice; he shall bring it a male without blemish.

And he shall kill it on the side of the altar northward before the Lord: and the priests, Aaron’s sons, shall sprinkle his blood round about upon the altar.
