Hebrews 7:5-7

New International Version

⁵ Now the law requires the descendants of Levi who become priests to collect a tenth from the people^(A)—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^(B) him who had the promises.^{(C) 7} And without doubt the lesser is blessed by the greater.
