The fire on the altar must be kept burning at all times. In it are burned the wholly consumed ascending offering; veins of fat from the peace, sin and guilt offerings; and the “handful” separated from the meal offering.
The kohanim eat the meat of the sin and guilt offerings, and the remainder of the meal offering. The peace offering is eaten by the one who brought it, except for specified portions given to the kohen. The holy meat of the offerings must be eaten by ritually pure persons, in their designated holy place and within their specified time.
Aaron and his sons remain within the Sanctuary compound for seven days, during which Moses initiates them into the priesthood.
