Leviticus 6:13-15

American Standard Version

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.
