Hebrews 7:5-9

Riverside(i) 5 And even those of the sons of Levi who attain the priesthood have command according to the Law to take a tenth from the people, their own brethren, although these have sprung from the loins of Abraham. 6 But he who had no genealogy from these took a tenth from Abraham and pronounced a blessing on him who had the promises. 7 Without dispute the less is blessed by the greater. 8 And here mortal men receive tenths, but there one of whom the witness is that he is living. 9 And, to put it frankly, Levi, who receives the tenths, was made to pay a tenth through Abraham.
