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!
