Leviticus 10:1-7 New Revised Standard Version (NRSV)
Nadab and Abihu
10 Now Aaron’s sons, Nadab and Abihu, each took his censer, put fire in it, and laid incense on it; and they offered unholy fire before the Lord, such as he had not commanded them. 2 And fire came out from the presence of the Lord and consumed them, and they died before the Lord. 3 Then Moses said to Aaron, “This is what the Lord meant when he said,
‘Through those who are near me
And Aaron was silent.
4 Moses summoned Mishael and Elzaphan, sons of Uzziel the uncle of Aaron, and said to them, “Come forward, and carry your kinsmen away from the front of the sanctuary to a place outside the camp.” 5 They came forward and carried them by their tunics out of the camp, as Moses had ordered. 6 And Moses said to Aaron and to his sons Eleazar and Ithamar, “Do not dishevel your hair, and do not tear your vestments, or you will die and wrath will strike all the congregation; but your kindred, the whole house of Israel, may mourn the burning that the Lord has sent. 7 You shall not go outside the entrance of the tent of meeting, or you will die; for the anointing oil of the Lord is on you.” And they did as Moses had ordered.
