Hebrews 7:5-7

New Century Version

⁵ Now the law says that those in the tribe of Levi who become priests must collect a tenth from the people—their own people—even though the priests and the people are from the family of Abraham. ⁶ Melchizedek was not from the tribe of Levi, but he collected a tenth from Abraham. And he blessed Abraham, the man who had God’s promises. ⁷ Now everyone knows that the more important person blesses the less important person.
