Numbers 16:4-12, 31-33

So when Moses heard it, he fell on his face; and he spoke to Korah and all his company, saying, “Tomorrow morning the LORD will show who is His and who is holy, and will cause him to come near to Him. That one whom He chooses He will cause to come near to Him. Do this: Take censers, Korah and all your company; put fire in them and put incense in them before the LORD tomorrow, and it shall be that the man whom the LORD chooses is the holy one. You take too much upon yourselves, you sons of Levi!” Then Moses said to Korah, “Hear now, you sons of Levi: Is it a small thing to you that the God of Israel has separated you from the congregation of Israel, to bring you near to Himself, to do the work of the tabernacle of the LORD, and to stand before the congregation to serve them; and that He has brought you near to Himself, you and all your brethren, the sons of Levi, with you? And are you seeking the priesthood also? Therefore you and all your company are gathered together against the LORD. And what is Aaron that you complain against him?” And Moses sent to call Dathan and Abiram the sons of Eliab, but they said, “We will not come up!

Now it came to pass, as he finished speaking all these words, that the ground split apart under them, and the earth opened its mouth and swallowed them up, with their households and all the men with Korah, with all their goods. So they and all those with them went down alive into the pit; the earth closed over them, and they perished from among the assembly.
