And Nadab and Abihu, the sons of Aaron, took each of them his censer, and put fire in it, and put incense thereon, and offered unholy fire before the LORD, which he commanded them not.
All Commentaries on Leviticus 10:1 Go To Leviticus 10
Cyprian of Carthage
AD 258
The sons of Aaron also, who set upon the altar a strange fire not commanded by the Lord, were at once blotted out in the sight of the avenging Lord. These examples, you will see, are being followed wherever the tradition which comes from God is despised by lovers of strange doctrine and replaced by teaching of merely human authority. –.
