Leviticus

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 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. ¹³Fire shall be kept burning upon the altar continually; it shall not go out. ¹⁴And this is the law of the meal offering: the sons of Aaron shall offer it before the Lord, before the altar. ¹⁵And 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 savour, as the memorial thereof, unto the Lord. ¹⁶And 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. ¹⁷It 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 guilt offering.
