Leviticus 10:1-4

¹But the sons of Aharon, Nadab and Abihu, took each man his censer and put fire in them, and put sweet incense upon it, and offered (or brought) before the Lord strange fire which He had not commanded them.

²And fire came out from before the Lord and consumed them, and they died before the Lord.

³And Mosheh said unto Aharon, This is that which the Lord spake, saying, In them who approacheth Me I will be sanctified, and in the face of all the people will I be glorified. And Aharon was silent.

⁴And Mosheh called to Mishael and to Elzaphan, the sons of Uzziel the uncle of Aharon, and said to them, Come nigh, and carry your brethren from before the sanctuary without the camp.
