Leviticus 10:1-4

¹And Nadab and Abihu, the sons of Aaron, took each his censer, and they put therein fire, and put thereon incense: and they brought near before the Lord a strange fire, which he had not commanded them.

²And there went out a fire from before the Lord, and consumed them, and they died before the Lord.

³Then said Moses unto Aaron, This is what the Lord hath spoken, saying, On those who are near unto me will I be sanctified, and before all the people will I be glorified: and Aaron held his peace.

⁴And Moses called unto Mishael and Elzaphan, the sons of 'Uzziel, the uncle of Aaron, and said unto them, Come near, carry your brethren from before the sanctuary to without the camp.
