Leviticus Chapter 10

10:1-2
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.
And there went out fire from the Lord, and devoured them, and they died before the Lord.

10:16-20
And Moses diligently sought the goat of the sin offering, and, behold, it was burnt: and he was angry with Eleazar and Ithamar, the sons of Aaron which were left alive, saying,
Wherefore have ye not eaten the sin offering in the holy place, seeing it is most holy, and God hath given it you to bear the iniquity of the congregation, to make atonement for them before the Lord?
Behold, the blood of it was not brought in within the holy place: ye should indeed have eaten it in the holy place, as I commanded.
And Aaron said unto Moses, Behold, this day have they offered their sin offering and their burnt offering before the Lord; and such things have befallen me: and if I had eaten the sin offering today, should it have been accepted in the sight of the Lord?
And when Moses heard that, he was content.
