Leviticus 6:9-12

9Command AaronH175 and his sonsH1121, saying, This is the law of the burnt-offering; this, the burnt-offering, shall be on the hearth on the altar all night unto the morning, and the fire of the altar shall be kept burning on it.

10And the priest shall putH5414 on his linen raiment, and his linen breeches shall he putH5414 on his flesh, and take up the ashes to which the fireH801 hath consumed the burnt-offering on the altar, and he shall putH5414 them beside the altar.

11And he shall put off his garments, and put on other garments, and carry forth the ashes without the camp unto a clean place.

12And the fire upon the altar shall be kept burning on it: it shall not be put out; and the priest shall burn wood on it every morning, and lay the burnt-offering in order upon it; and he shall burn thereon the fat of the peace-offerings.
