Hebrews 7:3-7

Without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like the Son of God, he remains a priest perpetually.

Now observe how great this man was to whom Abraham, the patriarch, gave a tenth of the choicest spoils.

And those indeed of the sons of Levi who receive the priest’s office have a commandment in the Law to collect a tenth from the people, that is, from their countrymen, although they are descended from Abraham.

But the one whose genealogy is not traced from them collected a tenth from Abraham and blessed the one who had the promises.

But without any dispute the lesser person is blessed by the greater.
