Hebrews 7:4–10

Consider how great Melchizedek was: Even the patriarch Abraham gave him a tenth of the plunder.

Now the law commands the sons of Levi who become priests to collect a tenth from the people—that is, from their brothers—though they too are descended from Abraham.

But Melchizedek, who did not trace his descent from Levi, collected a tenth from Abraham and blessed him who had the promises.

And indisputably, the lesser is blessed by the greater.

In the case of the Levites, mortal men collect the tenth; but in the case of Melchizedek, it is affirmed that he lives on.

And so to speak, Levi, who collects the tenth, paid the tenth through Abraham.

For when Melchizedek met Abraham, Levi was still in the loin of his ancestor.
