Numbers 16:5, 7, 10, 35, 40, 46-48

Then he said to Korah and all his followers: “Tomorrow morning the LORD will show who belongs to him. He will bring the one who is holy near to him; he will bring to himself the person he chooses.

Tomorrow put fire and incense in them and take them before the LORD. He will choose the man who is holy. You Levites have gone too far.”

He has brought you and all your fellow Levites near to himself, yet now you want to be priests.

Then a fire came down from the LORD and destroyed the two hundred fifty men who had presented the incense.

as the LORD had commanded him through Moses. These sheets were to remind the Israelites that only descendants of Aaron should burn incense before the LORD. Anyone else would die like Korah and his followers.

Then Moses said to Aaron, “Get your pan, and put fire from the altar and incense in it. Hurry to the people and remove their sin. The LORD is angry with them; the sickness has already started.” So Aaron did as Moses said. He ran to the middle of the people, where the sickness had already started among them. So Aaron offered the incense to remove their sin. He stood between the dead and the living, and the sickness stopped there.
