Leviticus 10:1-3

Revised Geneva Translation

10 But Nadab and Abihu, the sons of Aaron, each took his censor and put fire in it and put incense upon it and offered strange fire before the LORD, which He had not commanded them.

² Therefore, a fire went out from the LORD and devoured them. So they died before the LORD.

³ Then Moses said to Aaron, “This is it that the LORD spoke, saying, ‘I will be sanctified in those who come near Me. And I will be glorified before all the people.’” But Aaron held his peace.
