Leviticus 6:13
12. And 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.13. The fire shall ever be burning upon the altar; it shall never go out.14. And this is the law of the meat offering: the sons of Aaron shall offer it before the LORD, before the altar.
