Leviticus 10:1-2 Common English Bible (CEB)
Nadab and Abihu
10 Now Nadab and Abihu, two of Aaron’s sons, each took an incense pan. They put fire and incense on them and offered unauthorized fire before the Lord, which he had not commanded them. 2 Then fire flew out from before the Lord and devoured them, and they died before the Lord.
