Leviticus 6:8–18

⁸And Jehovah spoke to Moses, saying, ⁹Command Aaron and his sons, saying, This is the law of the burnt-offering; this, the burnt-offering, shall be on the hearth on the altar all night unto the morning, and the fire of the altar shall be kept burning on it. ¹⁰And the priest shall put on his linen raiment, and his linen breeches shall he put on his flesh, and take up the ashes to which the fire hath consumed the burnt-offering on the altar, and he shall put them beside the altar. ¹¹And he shall put off his garments, and put on other garments, and carry forth the ashes without the camp unto a clean place. ¹²And the fire upon the altar shall be kept burning on it: it shall not be put out; and the priest shall burn wood on it every morning, and lay the burnt-offering in order upon it; and he shall burn thereon the fat of the peace-offerings. ¹³A continual fire shall be kept burning on the altar: it shall never go out.

¹⁴And this is the law of the oblation: one of the sons of Aaron shall present it before Jehovah, before the altar. ¹⁵And he shall take of it his handful of the fine flour of the oblation, and of the oil thereof, and all the frankincense which is on the meat-offering, and shall burn it on the altar: it is a sweet odour of the memorial thereof to Jehovah. ¹⁶And the remainder thereof shall Aaron and his sons eat: unleavened shall it be eaten in a holy place; in the court of the tent of meeting shall they eat it. ¹⁷It shall not be baken with leaven. As their portion have I given it unto them of my offerings by fire: it is most holy; as the sin-offering, and as the trespass-offering. ¹⁸All the males among the children of Aaron shall eat of it. It is an everlasting statute in your generations, their portion of Jehovah’s offerings by fire: whatever toucheth these shall be holy.
