Hebrews 7:5-7

EJ2000(i) 5 And verily those that are of the sons of Levi, who receive the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they also have come out of the loins of Abraham; 6 but he whose descent is not counted in those took tithes from Abraham and blessed him that had the promises. 7 And without any contradiction the less is blessed of the better.
