Leviticus 6:11-12

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.
