Leviticus 10:1-5

Now Nadab and Abihu, the sons of Aaron, took their respective firepans, and after putting fire in them, placed incense on the fire and offered strange fire before the Lord, which He had not commanded them.

And fire came out from the presence of the Lord and consumed them, and they died before the Lord.

Then Moses said to Aaron, “It is what the Lord spoke, saying, ‘By those who come near Me I will be treated as holy, And before all the people I will be honored.’ ” So Aaron, therefore, kept silent.

Moses called also to Mishael and Elzaphan, the sons of Aaron’s uncle Uzziel, and said to them, “Come forward, carry your relatives away from the front of the sanctuary to an area outside of the camp.”

So they came forward and carried them, still in their tunics, to an area outside the camp, just as Moses had said.
