The Sin of Nadab and Abihu
1Aaron’s sons Nadab and Abihu put coals of fire in their incense burners and sprinkled incense over them. In this way, they disobeyed the Lord by burning before him the wrong kind of fire, different than he had commanded. 2So fire blazed forth from the Lord’s presence and burned them up, and they died there before the Lord.
