Numbers 16:3-11

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 the LORD is among them; wherefore then lift ye up yourselves above the assembly of the LORD?'

⁴And when Moses heard it, he fell upon his face.

⁵And he spoke unto Korah and unto all his company, saying: 'In the morning the LORD will show who are His, and who is holy, and will cause him to come near unto Him; even him whom He may choose will He cause to come near unto Him.

⁶This do: take you censors, Korah, and all his company;

⁷and put fire therein, and put incense upon them before the LORD to-morrow; and it shall be that the man whom the LORD doth choose, he shall be holy; ye take too much upon you, ye sons of Levi.'

⁸And Moses said unto Korah: 'Hear now, ye sons of Levi:

⁹is it but a small thing unto you, that the God of Israel hath separated you from the congregation of Israel, to bring you near to Himself, to do the service of the tabernacle of the LORD, and to stand before the congregation to minister unto them;

¹⁰and that He hath brought thee near, and all thy brethren the sons of Levi with thee? and will ye seek the priesthood also?

¹¹Therefore thou and all thy company that are gathered together against the LORD — ; and as to Aaron, what is he that ye murmur against him?'
