Leviticus 6:8-23

Then the LORD said to Moses, “Give Aaron and his sons the following instructions regarding the burnt offering. The burnt offering must be left on top of the altar until the next morning, and the fire on the altar must be kept burning all night. In the morning, after the priest on duty has put on his official linen clothing and linen undergarments, he must clean out the ashes of the burnt offering and put them beside the altar. Then he must take off these garments, change back into his regular clothes, and carry the ashes outside the camp to a place that is ceremonially clean. Meanwhile, the fire on the altar must be kept burning; it must never go out. Each morning the priest will add fresh wood to the fire and arrange the burnt offering on it. He will then burn the fat of the peace offerings on it. Remember, the fire must be kept burning on the altar at all times. It must never go out. “These are the instructions regarding the grain offering. Aaron’s sons must present this offering to the LORD in front of the altar. The priest on duty will take from the grain offering a handful of the choice flour moistened with olive oil, together with all the frankincense. He will burn this representative portion on the altar as a pleasing aroma to the LORD. Aaron and his sons may eat the rest of the flour, but it must be baked without yeast and eaten in a sacred place within the courtyard of the Tabernacle. Remember, it must never be prepared with yeast. I have given it to the priests as their share of the special gifts presented to me. Like the sin offering and the guilt offering, it is most holy. Any of Aaron’s male descendants may eat from the special gifts presented to the LORD. This is their permanent right from generation to generation. Anyone or anything that touches these offerings will become holy.” Then the LORD said to Moses, “On the day Aaron and his sons are anointed, they must present to the LORD the standard grain offering of two quarts of choice flour, half to be offered in the morning and half to be offered in the evening. It must be carefully mixed with olive oil and cooked on a griddle. Then slice this grain offering and present it as a pleasing aroma to the LORD. In each generation, the high priest who succeeds Aaron must prepare this same offering. It belongs to the LORD and must be burned up completely. This is a permanent law. All such grain offerings of a priest must be burned up entirely. None of it may be eaten.”
