Numbers 16:8-10

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

9seemeth 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 seek ye the priesthood also?
