Hebrews 7:2-18
English Standard Version
Chapter 7
2and to him Abraham apportioned a tenth part of everything. He is first, by translation of his name, king of righteousness, and then he is also king of Salem, that is, king of peace. 3He is without father or mother or genealogy, having neither beginning of days nor end of life, but resembling the Son of God he continues a priest forever.
4See how great this man was to whom Abraham the patriarch gave a tenth of the spoils!
5And those descendants of Levi who receive the priestly office have a commandment in the law to take tithes from the people, that is, from their brothers, though these also are descended from Abraham.
6But this man who does not have his descent from them received tithes from Abraham and blessed him who had the promises.
7It is beyond dispute that the inferior is blessed by the superior.
8In the one case tithes are received by mortal men, but in the other case, by one of whom it is testified that he lives.
9One might even say that Levi himself, who receives tithes, paid tithes through Abraham,
10for he was still in the loins of his ancestor when Melchizedek met him.
11Now if perfection had been attainable through the Levitical 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 Melchizedek, rather than one named after the order of Aaron?
12For when there is a change in the priesthood, there is necessarily a change in the law as well.
13For the one of whom these things are spoken belonged to another tribe, from which no one has ever served at the altar.
14For it is evident that our Lord was descended from Judah, and in connection with that tribe Moses said nothing about priests.
15This becomes even more evident when another priest arises in the likeness of Melchizedek,
16who has become a priest, not on the basis of a legal requirement concerning bodily descent, but by the power of an indestructible life.
17For it is witnessed of him, "You are a priest forever, after the order of Melchizedek."
