Hebrews 7:11-12

Revised Standard Version

Another Priest, Like Melchizedek

¹¹ Now if perfection had been attainable through the Levit′ical priesthood (for under it the people received the law), what further need would there have been for another priest to arise after the order of Melchiz′edek, rather than one named after the order of Aaron? ¹² For when there is a change in the priesthood, there is necessarily a change in the law as well.
