And Nadab and Abihu, the sons of Aaron, took either of them his censer, and put fire therein, and put incense thereon, and offered strange fire before the LORD, which he commanded them not.

Now Aaron’s sons Nadab and Abihu took their censers, put fire in them and added incense, and offered unauthorized fire before the LORD, contrary to His command.

And there went out fire from the LORD, and devoured them, and they died before the LORD.

So fire came out from the presence of the LORD and consumed them, and they died in the presence of the LORD.
