Hebrews 7:4-6

A priest like Melchizedek

⁴ See how great Melchizedek was! Abraham, the father of the people, gave him a tenth of everything he captured. ⁵ The descendants of Levi who receive the office of priest have a commandment under the Law to collect a tenth of everything from the people who are their brothers and sisters, though they also are descended from Abraham. ⁶ But Melchizedek, who isn’t related to them, received a tenth of everything from Abraham and blessed the one who had received the promises.
