Hebrews 7:11-16

Jesus Like Melchizedek 11If perfection could have been attained through the Levitical priesthood—and indeed the law given to the people established that priesthood—why was there still need for another priest to come, one in the order of Melchizedek, not in the order of Aaron? 12For when the priesthood is changed, the law must be changed also. 13He of whom these things are said belonged to a different tribe, and no one from that tribe has ever served at the altar. 14For it is clear that our Lord descended from Judah, and in regard to that tribe Moses said nothing about priests. 15And what we have said is even more clear if another priest like Melchizedek appears, 16one who has become a priest not on the basis of a regulation as to his ancestry but on the basis of the power of an indestructible life.
