Leviticus 10:1-2 New Life Version (NLV)
The Sin of Nadab and Abihu
10 Aaron’s sons, Nadab and Abihu, each took his fire pan, put fire in it, and put special perfume on it. They gave a fire that was not holy to the Lord because the Lord had not told them to do this. 2 So the Lord sent out fire that burned them up and they died before the Lord.
