Numbers 16:8-11

Then Moses said to Korah, “Hear now, you sons of Levi, is it not enough for you that the God of Israel has separated you from the rest of 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 to them; and that He has brought you near, Korah, and all your brothers, sons of Levi, with you? And are you seeking for the priesthood also? Therefore you and all your company are gathered together against the LORD; but as for Aaron, who is he that you grumble against him?”
