10. The next morning you will dress in your priestly clothes, including your linen underwear. Then clean away the ashes left by the sacrifices and pile them beside the altar.
11. Change into your everyday clothes, take the ashes outside the camp, and pile them in the special place.
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.
19. The Lord spoke to Moses
20. and told him what sacrifices the priests must offer on the morning and evening of the day they are ordained:It is the same as the regular morning and evening sacrifices—half a kilogramme of flour
21. mixed with olive oil and cooked in a shallow pan. The bread must then be crumbled into small pieces and sent up in smoke with a smell that pleases me.
22-23. Each of Aaron's descendants who is ordained as a priest must perform this ceremony and make sure that the bread is completely burnt on the altar. None of it may be eaten!
24. The Lord told Moses
25. how the priests from Aaron's family were to offer the sacrifice for sin:This sacrifice is very sacred, and the animal must be killed in my presence at the north side of the bronze altar.
