Leviticus 10:1-2 International Standard Version (ISV)
Nadab and Abihu
10 Aaron’s sons Nadab and Abihu each took his own censer, placed fire in it, covered it with incense, and brought it into the Lord’s presence as unauthorized fire that he had never prescribed for them. 2 As a result, fire came out from the Lord’s presence and incinerated them. They died while in the Lord’s presence.
