Leviticus 1:6

He shall lay his hand on the head of the burnt offering, and it shall be accepted for him to make atonement for him.

He shall kill the bull before Yahweh. Aaron's sons, the priests, shall present the blood and sprinkle the blood around on the altar that is at the door of the Tent of Meeting.

The sons of Aaron the priest shall put fire on the altar, and lay wood in order on the fire;

and Aaron's sons, the priests, shall lay the pieces, the head, and the fat in order on the wood that is on the fire which is on the altar;
