Leviticus 6:12-16

12The fire must always be burning on the altar. It must never go out. The priest will burn wood on it every morning. He will lay the burnt offering on the fire and burn the fat of the fellowship offering.

13The fire must always be burning on the altar. It must never go out.

14“These are the instructions for the grain offering. Aaron’s sons must bring it into the Lord’s presence in front of the altar.

15One of them will remove a handful of flour from the grain offering, together with the olive oil and all the incense. He will burn it on the altar as a reminder. It is a soothing aroma to the Lord.

16Aaron and his sons will eat the rest of it. They will eat unleavened bread in a holy place, in the courtyard of the tent of meeting.
