Leviticus 6:8-15

8Then the Lord spoke to Moses, saying,

9“Command Aaron and his sons, saying, ‘This is the law of the burnt offering: the burnt offering shall remain on the hearth that is on the altar all night until morning and the fire is to be kept burning on the altar.

10The priest is to put on his linen robe, with his linen undergarments next to his body. Then he shall take up the ashes of the burnt offering which the fire has consumed on the altar and put them beside the altar.

11Then he shall take off his garments and put on something else, and take the ashes outside the camp to a (ceremonially) clean place.

12The fire on the altar shall be kept burning; it shall not [be allowed to] go out. The priest shall burn wood on it every morning, and he shall arrange the burnt offering on it and offer the fat portions of the peace offerings up in smoke on it.

13The fire shall be burning continually on the altar; it shall not [be allowed to] go out.

14‘Now this is the law of the grain offering: the sons of Aaron shall present it before the Lord in front of the altar.

15One of them shall take up from it a handful of the fine flour of the grain offering with its oil and all the incense that is on the grain offering, and he shall offer it up in smoke on the altar, a sweet and soothing aroma, as the memorial offering to the Lord.
