12 The fire must never go out, so put wood on it each morning. After this, you are to lay an animal on the altar next to the fat that you sacrifice to ask my blessing. Then send it all up in smoke to me.
13 The altar fire must always be kept burning—it must never go out.
14 When someone offers a sacrifice to give thanks to me, the priests from Aaron's family must bring it to the front of the bronze altar,
15 where one of them will scoop up a handful of the flour and oil, together with all the incense on it. Then, to show that the whole offering belongs to me, he will lay all of this on the altar and send it up in smoke with a smell that pleases me.
16-17 The rest of it is to be baked without yeast and eaten by the priests in the sacred courtyard of the sacred tent. This bread is very holy, just like the sacrifices for sin or for making things right, and I have given this part to the priests from what is offered to me on the altar.
18 Only the men in Aaron's family are allowed to eat this bread, and they must go through a ceremony to be made holy before touching it. This law will never change.
