Hebrews 7:5-7

Lamsa(i) 5 For those sons of Levi who received the office of the priesthood, were authorized by law to take tithes from the people; even from their own brethren who also had come out of the loins of Abraham. 6 But this man who is not recorded in their genealogies took tithes even from Abraham, and blessed him who had received the promises. 7 Beyond dispute: he who was less was blessed by him who was greater than himself.
