HEB 7:11

11 Therefore if perfection was by the priesthood of Levi, for under him the people took the law, what yet was it needful, (for) another priest to rise, by the order of Melchisedec, and not to be said by the order of Aaron? (And so if perfection had truly come by means of the priesthood of the sons of Levi, for under him the people received the Law, why then was it still necessary for another priest to arise, by the order of Melchizedek, and not to be called by, or to come from, the order of Aaron?)
