Numbers 16:1-7

Now Korah the son of Izhar, the son of Kohath, the son of Levi, with Dathan and Abiram the sons of Eliab, and On the son of Peleth, descendants of Reuben, took action, and they rose up [in rebellion] before Moses, together with some of the Israelites, two hundred and fifty leaders of the congregation chosen in the assembly, men of distinction. They assembled together against Moses and Aaron, and said to them, “You have gone far enough, for all the congregation are holy, every one of them, and the LORD is among them. Why then do you exalt yourselves above the assembly of the LORD?” And when Moses heard this, he fell face downward; and he spoke to Korah and all his company, saying, “In the morning the LORD will show who belongs to Him, and who is holy, and will bring him near to Himself; the one whom He will choose He will bring near to Himself. [2 Tim 2:19] Do this: Take censers for yourselves, Korah and all your company, then put fire in them and place incense on them in the presence of the LORD tomorrow; and the man whom the LORD chooses shall be the one who is holy. You have gone far enough, you sons of Levi.”
