Lev 6:8-13

Instructions concerning Sacrifices 8 The Lord spoke to Moses, saying:9Command Aaron and his sons, saying: This is the ritual of the burnt offering. The burnt offering itself shall remain on the hearth upon the altar all night until the morning, while the fire on the altar shall be kept burning.10The priest shall put on his linen vestments after putting on his linen undergarments next to his body; and he shall take up the ashes to which the fire has reduced the burnt offering on the altar, and place them beside the altar.11Then he shall take off his vestments and put on other garments, and carry the ashes out to a clean place outside the camp.12The fire on the altar shall be kept burning; it shall not go out. Every morning the priest shall add wood to it, lay out the burnt offering on it, and turn into smoke the fat pieces of the offerings of well-being.13A perpetual fire shall be kept burning on the altar; it shall not go out.
