Leviticus 10:1-4

¹And the two sons of Aaron, Nadab and Abiud, took each his censer, and put fire therein, and threw incense thereon, and offered strange fire before the Lord, which the Lord did not command them,

²and fire came forth from the Lord, and devoured them, and they died before the Lord.

³And Moses said to Aaron, This is the thing which the Lord spoke, saying, I will be sanctified among them that draw night to me, and I will be glorified in the whole congregation; and Aaron was pricked in his heart.

⁴And Moses called Misadae, and Elisaphan, sons of Oziel, sons of the brother of Aaron's father, and said to them, Draw near and take your brethren from before the sanctuary out of the camp.
