Leviticus 6:14

11 And he shall put off his garments, and put on other garments, and carry forth the ashes without the camp unto a clean place.

12 And the fire upon the altar shall be kept burning thereon, it shall not go out; and the priest shall burn wood on it every morning: and he shall lay the burnt-offering in order upon it, and shall burn thereon the fat of the peace-offerings.

13 Fire shall be kept burning upon the altar continually; it shall not go out.

14 And this is the law of the meal-offering: the sons of Aaron shall offer it before Jehovah, before the altar.

15 And he shall take up therefrom his handful, of the fine flour of the meal-offering, and of the oil thereof, and all the frankincense which is upon the meal-offering, and shall burn it upon the altar for a sweet savor, as the memorial thereof, unto Jehovah.

16 And that which is left thereof shall Aaron and his sons eat: it shall be eaten without leaven in a holy place; in the court of the tent of meeting they shall eat it.

17 It shall not be baken with leaven. I have given it as their portion of my offerings made by fire; it is most holy, as the sin-offering, and as the trespass-offering.
