Hebrews 7:5-7

American Standard Version

⁵ And they indeed of the sons of Levi that receive the priest’s office have commandment to take tithes of the people according to the law, that is, of their brethren, though these have come out of the loins of Abraham: ⁶ but he whose genealogy is not counted from them hath taken tithes of Abraham, and hath blessed him that hath the promises. ⁷ But without any dispute the less is blessed of the better.
