Leviticus 10:8,9

Some have thought from this precept, that the sin of Aaron's sons was drunkenness. It is possible that Nadab and Abihu might have been intoxicated at the time they offered the strange fire. But then, though this horrid state of drunkenness might have been in some degree instrumental to the commission of the sin for which GOD smote them, certain it is, that this was not the sin itself. For it is expressly said, that the offering of strange fire was the crime. Reader! pause over the account, and think how awful it must be in any, and how infinitely more so in ministers, to be given to wine, wherein is excess. And what a daring act of impiety in a state of this kind, to rush into the divine presence. LORD! keep the souls of men by thy grace from such presumptuous sins; Luke 21:34.
