Leviticus 6:11

7The priest shall make atonement for him before the LORD, and he will be forgiven concerning whatever he does to become guilty.”

8The LORD spoke to Moses, saying,

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

10The priest shall put on his linen garment, and he shall put on his linen trousers upon his body; and he shall remove the ashes from where the fire has consumed the burnt offering on the altar, and he shall put them beside the altar.

11He shall take off his garments, and put on other garments, and carry the ashes outside the camp to a clean place.

12The fire on the altar shall be kept burning on it, it shall not go out; and the priest shall burn wood on it every morning. He shall lay the burnt offering in order upon it, and shall burn on it the fat of the peace offerings.

13Fire shall be kept burning on the altar continually; it shall not go out.

14“‘This is the law of the meal offering: the sons of Aaron shall offer it before the LORD, before the altar.

15He shall take from there his handful of the fine flour of the meal offering, and of its oil, and all the frankincense which is on the meal offering, and shall burn it on the altar for a pleasant aroma, as its memorial portion, to the LORD.
