Leviticus 6:11-13

Young's Literal Translation

¹¹ and he hath stripped off his garments, and hath put on other garments, and hath brought out the ashes unto the outside of the camp, unto a clean place.

¹² `And the fire on the altar is burning on it, it is not quenched, and the priest hath burned on it wood morning by morning, and hath arranged on it the burnt-offering, and hath made perfume on it [with] the fat of the peace-offerings;

¹³ fire is continually burning on the altar, it is not quenched.
