Leviticus 6:9-11

New Revised Standard Version, Anglicised Catholic Edition

⁹ Command Aaron and his sons, saying: This is the ritual of the burnt-offering. The burnt-offering itself shall remain on the hearth upon the altar all night until the morning, while the fire on the altar shall be kept burning. ¹⁰ The priest shall put on his linen vestments after putting on his linen undergarments next to his body; and he shall take up the ashes to which the fire has reduced the burnt-offering on the altar, and place them beside the altar. ¹¹ Then he shall take off his vestments and put on other garments, and carry the ashes out to a clean place outside the camp.
