Leviticus 6:12-18

¹²And the fire upon the altar shall be burning in 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.

¹³The fire shall ever be burning upon the altar; it shall never go out.

¹⁴And this is the law of the meat offering: the sons of Aaron shall offer it before the Lord, before the altar.

¹⁵And he shall take of it his handful, of the flour of the meat offering, and of the oil thereof, and all the frankincense which is upon the meat offering, and shall burn it upon the altar for a sweet savour, even the memorial of it, unto the Lord.

¹⁶And the remainder thereof shall Aaron and his sons eat: with unleavened bread shall it be eaten in the holy place; in the court of the tabernacle of the congregation they shall eat it.

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

¹⁸All the males among the children of Aaron shall eat of it. It shall be a statute for ever in your generations concerning the offerings of the Lord made by fire: every one that toucheth them shall be holy.
