8The LORD spoke to Moses, saying:9Command Aaron and his sons, saying: This is the instruction of the burnt offering. It is the burnt offering upon the hearth on the altar all night until morning, and the fire of the altar shall burn on it.10The priest shall put on his linen garment and linen undergarments upon his flesh; he shall remove the ashes that the fire has consumed of the burnt offering upon the altar and place them beside the altar.11He shall take off his garments and put on other garments, then carry the ashes outside the camp to a clean place.12The fire on the altar shall burn on it; it shall not go out. The priest shall kindle wood on it in the morning, and arrange the burnt offering upon it, and burn the fat of the peace offerings on it.13Fire shall burn continually upon the altar; it shall not go out.
