Hebrews 7:7-10

7And without doubt the lesser is blessed by the greater. 8In the one case, the tenth is collected by people who die; but in the other case, by him who is declared to be living. 9One might even say that Levi, who collects the tenth, paid the tenth through Abraham,

10because when Melchizedek met Abraham, Levi was still in the body of his ancestor.
