Hebrews 7:11-14

11Therefore, if perfection were through the Levitical priesthood (for under it the people received the law), what further need was there that another priest should rise according to the order of Melchizedek, and not be called according to the order of Aaron?

12For the priesthood being changed, of necessity there is also a change of the law.

13For He of whom these things are spoken belongs to another tribe, from which no man has officiated at the altar.

14For it is evident that our Lord arose from Judah, of which tribe Moses spoke nothing concerning priesthood.
