Hebrews 7:5–9

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. This man, however, did not trace his descent from Levi, yet he collected a tenth from Abraham and blessed him who had the promises. And without doubt the lesser is blessed by the greater. 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. One might even say that Levi, who collects the tenth, paid the tenth through Abraham,

The sons of Levi who receive the priestly office have a command according to the law to collect a tenth from the people—that is, from their brothers and sisters—though they have also descended from Abraham. But one without this lineage collected a tenth from Abraham and blessed the one who had the promises. Without a doubt, the inferior is blessed by the superior. In the one case, men who will die receive a tenth, but in the other case, Scripture testifies that he lives. And in a sense Levi himself, who receives a tenth, has paid a tenth through Abraham,

Now the law of Moses required that the priests, who are descendants of Levi, must collect a tithe from the rest of the people of Israel, who are also descendants of Abraham. But Melchizedek, who was not a descendant of Levi, collected a tenth from Abraham. And Melchizedek placed a blessing upon Abraham, the one who had already received the promises of God. And without question, the person who has the power to give a blessing is greater than the one who is blessed.

The priests who collect tithes are men who die, so Melchizedek is greater than they are, because we are told that he lives on. In addition, we might even say that these Levites—the ones who collect the tithe—paid a tithe to Melchizedek when their ancestor Abraham paid a tithe to him.

And indeed those of the sons of Levi who receive the priesthood have a commandment to collect a tenth from the people according to the law, that is, from their brothers, although they are descended from Abraham. But the one who did not trace his descent from them collected tithes from Abraham and blessed the one who had the promises. Now without any dispute the inferior is blessed by the more prominent. And in this case mortal men receive tithes, but in that case it is testified that he lives. And, so to speak, even Levi, the one who receives tithes, has paid tithes through Abraham.

And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham: But he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises. And without all contradiction the less is blessed of the better. And here men that die receive tithes; but there he receiveth them, of whom it is witnessed that he liveth. And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham.
