Hebrews 7:4-6

King James Version

⁴ Now consider how great this man was, unto whom even the patriarch Abraham gave the tenth of the spoils.

⁵ 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:

⁶ But he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises.
