Leviticus 6:8-13

8The Lord spoke to Moses,

9“Command Aaron and his sons: These are the instructions for the burnt offering that stays on the altar overnight while the altar fire is kept burning.

10“The priest must put on his linen clothes, including his linen undergarments. Then he will remove the ashes left on the altar from the fire that consumed the burnt offering and will put them next to the altar.

11Then he will take off these clothes and put on some others. He will take the ashes to a clean place outside the camp.

12The fire must always be burning on the altar. It must never go out. The priest will burn wood on it every morning. He will lay the burnt offering on the fire and burn the fat of the fellowship offering.

13The fire must always be burning on the altar. It must never go out.
