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, sons of Reuben, took men; and they rose up before Moses with some of the children of Israel, two hundred and fifty leaders of the congregation, representatives of the congregation, men of renown. They gathered together against Moses and Aaron, and said to them, “You take too much upon yourselves, for all the congregation is holy, every one of them, and the LORD is among them. Why then do you exalt yourselves above the assembly of the LORD?” 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!”
