Leviticus 1:7-12

The sons of Aaron the priest will prepare a fire on the altar and arrange wood on the fire. Aaron’s sons the priests are to arrange the pieces, the head, and the fat  on top of the burning wood on the altar. The offerer is to wash its entrails  and legs  with water. Then the priest will burn all of it on the altar as a burnt offering, a food offering,  a pleasing aroma  to the Lord. “But if his offering for a burnt offering is from the flock, from sheep or goats,  he is to present an unblemished male. He will slaughter it on the north side of the altar before the Lord. Aaron’s sons the priests will splatter its blood against the altar on all sides. He will cut the animal into pieces with its head and its fat, and the priest will arrange them on top of the burning wood on the altar.
