Leviticus 6:8-15

8The Lord said to Moses,

9‘Tell Aaron and his sons my rules. They must burn these gifts on the altar. The fire must burn all night.

10When the morning comes, the priest must dress himself in his linen clothes. The linen must be next to his skin. He must take the ashes from the fire and he must put them at the side of the altar.

11Then he must dress himself in other clothes. He must carry the ashes outside the camp and he must put them in a special place.

12The fire that is on the altar must never stop burning. Every morning the priest must put wood on it. He must also put on it the gifts and the fat of the friendship offerings.

13The fire must always burn. It must not go out.

14These are the rules for the gift of grain. Aaron's sons must bring it in front of the altar to give to the Lord.

15A priest must take some of the flour and oil. He must mix this special part with incense and he must burn all of it on the altar. The smell of them while they are burning will give the Lord pleasure.
