Numbers (The Fourth Book of Moses, Commonly Called )

Now Korah son of Izhar son of Kohath son of Levi, along with Dathan and Abiram sons of Eliab, and On son of Peleth--descendants of Reuben--took

two hundred fifty Israelite men, leaders of the congregation, chosen from the assembly, well-known men, and they confronted Moses.

They assembled against Moses and against Aaron, and said to them, "You have gone too far! All the congregation are holy, everyone of them, and the LORD is among them. So why then do you exalt yourselves above the assembly of the LORD?"

When Moses heard it, he fell on his face.

Then he said to Korah and all his company, "In the morning the LORD will make known who is his, and who is holy, and who will be allowed to approach him; the one whom he will choose he will allow to approach him.
