Hebrews 7:4-6

Sawyer(i) 4 (2:7) And behold, how great this man was, to whom even Abraham the patriarch gave a tenth of the spoils. 5 And the sons of Levi who receive the priesthood, have a commandment to tithe the people according to the law, that is their brothers, although descended from Abraham; 6 but he whose descent is not reckoned from them received tithes of Abraham, and blessed him who has the promises.
