Leviticus 10:1-4

¹And Nadab and Abihu, the sons of Aaron, took each of them his censer, and put fire therein, and laid incense thereon, and offered strange fire before the LORD, which He had not commanded them.

²And there came forth fire from before the LORD, and devoured them, and they died before the LORD.

³Then Moses said unto Aaron: 'This is it that the LORD spoke, saying: Through them that are nigh unto Me I will be sanctified, and before all the people I will be glorified.' And Aaron held his peace.

⁴And Moses called Mishael and Elzaphan, the sons of Uzziel the uncle of Aaron, and said unto them: 'Draw near, carry your brethren from before the sanctuary out of the camp.'
