Hebrews 7:4-17 New Revised Standard Version (NRSV)
4 See how great he is! Even[a] Abraham the patriarch gave him a tenth of the spoils. 5 And those descendants of Levi who receive the priestly office have a commandment in the law to collect tithes[b] from the people, that is, from their kindred,[c] though these also are descended from Abraham. 6 But this man, who does not belong to their ancestry, collected tithes[d] from Abraham and blessed him who had received the promises. 7 It is beyond dispute that the inferior is blessed by the superior. 8 In the one case, tithes are received by those who are mortal; in the other, by one of whom it is testified that he lives. 9 One might even say that Levi himself, who receives tithes, paid tithes through Abraham, 10 for he was still in the loins of his ancestor when Melchizedek met him.
Another Priest, Like Melchizedek
11 Now if perfection had been attainable through the levitical priesthood—for the people received the law under this priesthood—what further need would there have been to speak of another priest arising according to the order of Melchizedek, rather than one according to the order of Aaron? 12 For when there is a change in the priesthood, there is necessarily a change in the law as well. 13 Now the one of whom these things are spoken belonged to another tribe, from which no one has ever served at the altar. 14 For it is evident that our Lord was descended from Judah, and in connection with that tribe Moses said nothing about priests.
15 It is even more obvious when another priest arises, resembling Melchizedek, 16 one who has become a priest, not through a legal requirement concerning physical descent, but through the power of an indestructible life. 17 For it is attested of him,
“You are a priest forever,
Hebrews 7:4-17 New International Version (NIV)
4 Just think how great he was: Even the patriarch Abraham gave him a tenth of the plunder! 5 Now the law requires the descendants of Levi who become priests to collect a tenth from the people—that is, from their fellow Israelites—even though they also are descended from Abraham. 6 This man, however, did not trace his descent from Levi, yet he collected a tenth from Abraham and blessed him who had the promises. 7 And without doubt the lesser is blessed by the greater. 8 In the one case, the tenth is collected by people who die; but in the other case, by him who is declared to be living. 9 One might even say that Levi, who collects the tenth, paid the tenth through Abraham, 10 because when Melchizedek met Abraham, Levi was still in the body of his ancestor.
Jesus Like Melchizedek
11 If 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? 12 For when the priesthood is changed, the law must be changed also. 13 He of whom these things are said belonged to a different tribe, and no one from that tribe has ever served at the altar. 14 For it is clear that our Lord descended from Judah, and in regard to that tribe Moses said nothing about priests. 15 And what we have said is even more clear if another priest like Melchizedek appears, 16 one 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. 17 For it is declared:
“You are a priest forever,
