Leviticus 6:11-13

New Catholic Bible

¹¹ Then he will take off those clothes and put on others and carry the ashes outside the camp to a clean place. ¹² The fire on the altar will be kept burning; it will not be extinguished. The priest shall burn wood on it every morning, and he shall lay burnt offerings on it and burn the fat of the peace offerings upon it. ¹³ The fire must always be kept burning on the altar. It must never go out.
