Leviticus 1:10-13

“If the animal you present as a burnt offering is from the flock, it may be either a sheep or a goat, but it must be a male with no defects. Slaughter the animal on the north side of the altar in the LORD’s presence, and Aaron’s sons, the priests, will splatter its blood against all sides of the altar. Then cut the animal in pieces, and the priests will arrange the pieces of the offering, including the head and fat, on the wood burning on the altar. But the internal organs and the legs must first be washed with water. Then the priest will burn the entire sacrifice on the altar as a burnt offering. It is a special gift, a pleasing aroma to the LORD.
