Leviticus 6:9-13 - Sacrificial Instructions For The Priests: The Burnt Offering

⁹ "Deliver these orders to Aaron and his sons concerning the regulations for burnt offerings: The burnt offering is to remain on the hearth of the altar throughout the entire night until morning, and the fire on the altar is to be kept burning along with it. ¹⁰ The priest is to clothe himself with a linen robe and undergarments. Then he is to take the ashes of the burnt offering on the altar that had been consumed by the fire and set them beside the altar. ¹¹ Then he is to change his clothes, dressing himself with a different set of clothes, and take the ashes to a clean place outside the camp. ¹² The fire on the altar is to be kept burning continuously without being extinguished. The priest is to burn wood on it every morning, arrange burnt offerings over it, and then burn the fat contained in the peace offerings over it. ¹³ The fire is to continue to burn on the altar and is never to be extinguished."
