Leviticus 6:13

‘If his offering is a burnt offering from the herd, he shall bring it near, a male without blemish; he shall bring it near to the doorway of the tent of meeting, that he may be accepted before Yahweh.

‘And the sons of Aaron the priest shall put fire on the altar and arrange wood on the fire.

“Command Aaron and his sons, saying, ‘This is the law for the burnt offering: the burnt offering itself shall remain on the hearth on the altar all night until the morning, and the fire on the altar shall be kept burning on it.

but the chamber which faces toward the north is for the priests who keep the responsibility of the altar. These are the sons of Zadok, who from the sons of Levi come near to Yahweh to minister to Him.”
