Hebrews 7:5-7

New International Version - UK

⁵ Now the law requires the descendants of Levi who become priests to collect a tenth from the people – that is, from their fellow Israelites – even though they also are descended from Abraham. ⁶ This man, however, did not trace his descent from Levi, yet he collected a tenth from Abraham and blessed him who had the promises. ⁷ And without doubt the lesser is blessed by the greater.
