Leviticus 6:12-13

New American Standard Bible

¹² The fire on the altar shall be kept burning on it. It shall not go out, but the priest shall burn wood on it every morning; and he shall lay out the burnt offering on it, and offer up in smoke the fat portions of the peace offerings ^(A)on it. ¹³ Fire shall be kept burning continually on the altar; it is not to go out.
