Leviticus 6:10–16

¹⁰The 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. ¹²The fire on the altar shall be kept burning; it shall not go out. Every morning the priest shall add wood to it, lay out the burnt offering on it, and turn into smoke the fat pieces of the offerings of well-being. ¹³A perpetual fire shall be kept burning on the altar; it shall not go out.

¹⁴“This is the rule of the grain offering: The sons of Aaron shall offer it before the Lord, in front of the altar.^{* 15}They shall take from it a handful of the choice flour and oil of the grain offering, with all the frankincense that is on the offering, and they shall turn its memorial portion into smoke on the altar as a pleasing odor to the Lord. ¹⁶Aaron and his sons shall eat what is left of it; it shall be eaten as unleavened cakes in a holy place; in the court of the tent of meeting they shall eat it.^*
