Hebrews 7:4-6

International Standard Version

⁴ Just look at how great this man was! Even Abraham—the patriarch himself—gave him a tenth of what he had captured! ⁵ The descendants of Levi who accept the priesthood have a commandment in the Law to collect a tenth from the people, that is, from their own brothers, even though they are also descendants of Abraham. ⁶ But this man, whose descent is not traced from them, collected a tenth from Abraham and blessed the man who had received the promises.
