Leviticus 1:9-13

9But 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 Yhwh.

10And 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. 11And he shall kill it on the side of the altar northward before Yhwh: and the priests, Aaron’s sons, shall sprinkle his blood round about upon the altar. 12And he shall cut it into his pieces, with his head and his fat: and the priest shall lay them in order on the wood that is on the fire which is upon the altar: 13But he shall wash the inwards and the legs with water: and the priest shall bring it all, and burn it upon the altar: it is a burnt sacrifice, an offering made by fire, of a sweet savour unto Yhwh.
