A fire flashed from Jehovah and burned them. They died in the presence of Jehovah.

Nadab and Abihu died because they offered unauthorized fire in Jehovah's presence.

Jehovah said to Moses: You and Aaron, Nadab, Abihu, and seventy of Israel's elders come up the mountain to me and worship at a distance.

Moses and Aaron, together with Nadab and Abihu and the seventy leaders, went up the mountain.

Then ordain them, because they and their descendants will have a long lasting priesthood.

Moses spoke to Aaron and his two remaining sons, Eleazar and Ithamar. He said: Take the grain offering that is left over from the food offered to Jehovah. Bake unleavened bread with it and eat it beside the altar. This is because this offering is very holy.

The priest Eleazar took the copper incense burners that had been brought by those who had been burned to death. The incense burners were then hammered into thin metal sheets to cover the altar.

Only you and your sons may do the work of priests, everything done at the altar and under the canopy. This is my gift to you: You may serve me as priests. Anyone else who comes near the holy place to do this work must die.
