The LORD said to Moses:
“Give Aaron and his sons this command: ‘These are the regulations for the burnt offering: The burnt offering is to remain on the altar hearth throughout the night, till morning, and the fire must be kept burning on the altar.
The priest shall then put on his linen clothes, with linen undergarments next to his body, and shall remove the ashes of the burnt offering that the fire has consumed on the altar and place them beside the altar.
Then he is to take off these clothes and put on others, and carry the ashes outside the camp to a place that is ceremonially clean.
The fire on the altar must be kept burning; it must not go out. Every morning the priest is to add firewood and arrange the burnt offering on the fire and burn the fat of the fellowship offerings on it.
The fire must be kept burning on the altar continuously; it must not go out.
“ ‘These are the regulations for the grain offering: Aaron’s sons are to bring it before the LORD, in front of the altar.
The priest is to take a handful of the finest flour and some olive oil, together with all the incense on the grain offering, and burn the memorial portion on the altar as an aroma pleasing to the LORD.
Aaron and his sons shall eat the rest of it, but it is to be eaten without yeast in the sanctuary area; they are to eat it in the courtyard of the tent of meeting.
It must not be baked with yeast; I have given it as their share of the food offerings presented to me. Like the sin offering and the guilt offering, it is most holy.
Any male descendant of Aaron may eat it. For all generations to come it is his perpetual share of the food offerings presented to the LORD. Whatever touches them will become holy. ’ ”
