Hebrews 7:4-6

Noyes(i) 4 Consider now how great this man was, to whom even Abraham the patriarch gave a tenth of the spoils. 5 And those indeed of the sons of Levi who receive the office of the priesthood have a command to take tithes of the people by the Law, that is, of their brethren, though they have come out of the loins of Abraham; 6 but he whose descent is not reckoned from them took tithes of Abraham, and blessed him who had the promises.
