Leviticus 6:10-12

New Century Version

¹⁰ The priest must put on his linen robe and linen underclothes next to his body. Then he will remove the ashes from the burnt offering on the altar and put them beside the altar. ¹¹ Then he must take off those clothes and put on others and carry the ashes outside the camp to a special clean place. ¹² But the fire must be kept burning on the altar; it must not be allowed to go out. The priest must put more firewood on the altar every morning, place the whole burnt offering on the fire, and burn the fat of the fellowship offerings.
