Leviticus 6:8-11

⁸And the Lord spake to Moses, and said,

⁹Command thou to Aaron, and to his sons, This is the law of burnt sacrifice; it shall be burnt in the altar all night till the morrow; fire that is given from heaven shall be of the same altar.

¹⁰The priest shall be clothed with a coat, and with linen breeches; and he shall take away the ashes, which the fire devouring hath burnt out, and he shall put those beside the altar;

¹¹and he shall be spoiled of the former clothes, and he shall be clothed with other, and he shall bear those ashes out of the tents, and in a most clean place he shall make them to be wasted, or quenched, till to a dead spark.
