Hebrews 7:6-8

New Living Translation

⁶ But Melchizedek, who was not a descendant of Levi, collected a tenth from Abraham. And Melchizedek placed a blessing upon Abraham, the one who had already received the promises of God. ⁷ And without question, the person who has the power to give a blessing is greater than the one who is blessed.

⁸ The priests who collect tithes are men who die, so Melchizedek is greater than they are, because we are told that he lives on.
