Leviticus 10:1-4

¹Nadab and Abihu, sons of Aaron, each took his censer, put fire in it, and then incense. Then they offered unapproved fire before Yahweh, which he had not commanded them to offer.

²So fire came out from before Yahweh and devoured them, and they died before Yahweh.

³Then Moses said to Aaron, “This is what Yahweh was talking about when he said, 'I will reveal my holiness to those who come near me. I will be glorified before all the people.'” Aaron did not say anything.

⁴Moses called Mishael and Elzaphan, the sons of Uzziel the uncle of Aaron, and said to them, “Come here and carry your brothers out of the camp from before the tabernacle.”
