Leviticus 6:8-11

8And Jehovah spake unto Moses, saying, 9Command AaronH175 and his sonsH1121, saying, This is the law of the burnt-offering: the burnt-offering shall be on the hearth upon the altar all night unto the morning; and the fire of the altar shall be kept burning thereon. 10And the priest shall putH5414 on his linen garment, and his linen breeches shall he putH5414 upon his flesh; and he shall take up the ashes whereto 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.
