1. Nadab and Abihu were two of Aaron's sons, but they disobeyed the Lord by burning incense to him on a fire pan, when they were not supposed to.
2. Suddenly the Lord sent fiery flames and burnt them to death.
3. Then Moses told Aaron that this was exactly what the Lord had meant when he said:“I demand respectfrom my priests,and I will be praisedby everyone!”Aaron was speechless.
4. Moses sent for Mishael and Elzaphan, the two sons of Aaron's uncle Uzziel. Then he told them, “Take these two dead relatives of yours outside the camp far from the entrance to the sacred tent.”
5. So they dragged the dead men away by their clothes.
6. Then Moses told Aaron and his other two sons, Eleazar and Ithamar:Don't show your sorrow by leaving your hair uncombed and tearing your priestly clothes, or the Lord will get angry. He will kill the three of you and punish everyone else. It's all right for your relatives, the people of Israel, to mourn for those he destroyed by fire.
7. But you are the Lord's chosen priests, and you must not leave the sacred tent, or you will die.Aaron and his two sons obeyed Moses.
8. The Lord said to Aaron:
9. When you or your sons enter the sacred tent, you must never drink beer or wine. If you do, you will die there! This law will never change.
10. You must learn the difference between what is holy and what isn't holy and between the clean and the unclean.
11. You must also teach the people of Israel everything that I commanded Moses to say to them.
