Hebrews 7:9-11

Complete Jewish Bible

⁹ One might go even further and say that Levi, who himself receives tenths, paid a tenth through Avraham; ¹⁰ inasmuch as he was still in his ancestor Avraham’s body when Malki-Tzedek met him.

¹¹ Therefore, if it had been possible to reach the goal through the system of cohanim derived from Levi (since in connection with it, the people were given the Torah), what need would there have been for another, different kind of cohen, the one spoken of as to be compared with Malki-Tzedek and not to be compared with Aharon?
