Leviticus 1:9-13

9but its inwards and its legs shall he wash with water. And the priest shall burn the whole on the altar, for a burnt-offering, an offering made by fire, of a sweet savor unto Jehovah.

10And if his oblation be of the flock, of the sheep, or of the goats, for a burnt-offering; he shall offer it a male without blemish. 11And he shall kill it on the side of the altar northward before Jehovah: and Aaron’s sons, the priests, shall sprinkle its blood upon the altar round about. 12And he shall cut it into its pieces, with its head and its fat; and the priest shall lay them in order on the wood that is on the fire which is upon the altar: 13but the inwards and the legs shall he wash with water. And the priest shall offer the whole, and burn it upon the altar: it is a burnt-offering, an offering made by fire, of a sweet savor unto Jehovah.
