Hebrews 7:4–12

⁴See how great he is! Abraham the patriarch gave him a tithe 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 brethren, though these also are descended from Abraham. ⁶But this man who has not their genealogy received tithes from Abraham and blessed him who had the promises. ⁷It is beyond dispute that the inferior is blessed by the superior. ⁸Here tithes are received by mortal men; there, 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.
