Numbers 16:8-11

And Moses said unto Korah, Hear, I pray you, ye sons of Levi: seemeth 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? And he hath brought thee near to him, and all thy brethren the sons of Levi with thee: and seek ye the priesthood also? For which cause both thou and all thy company are gathered together against the LORD: and what is Aaron, that ye murmur against him?
