Numbers 16:1-7

1Now 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, tookmen: 2and they rose up before Moses, with certain of the children of Israel, two hundred and fifty princes of the congregation, called to the assembly, men of renown; 3and they assembled themselves together against Moses and against Aaron, and said unto them, Ye take too much upon you, seeing all the congregation are holy, every one of them, and Jehovah is among them: wherefore then lift ye up yourselves above the assembly of Jehovah?

4And when Moses heard it, he fell upon his face: 5and he spake unto Korah and unto all his company, saying, In the morning Jehovah will show who are his, and who is holy, and will cause him to come near unto him: even him whom he shall choose will he cause to come near unto him. 6This do: take you censers, Korah, and all his company; 7and put fire in them, and put incense upon them before Jehovah to-morrow: and it shall be that the man whom Jehovah doth choose, he shall be holy: ye take too much upon you, ye sons of Levi.
