Hebrews 7:2-6

2to whom also Abraham gave a tenth part of all, first being translated “king of righteousness,” and then also king of Salem, meaning “king of peace,”

3without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like the Son of God, remains a priest continually.

4Now consider how great this man was, to whom even the patriarch Abraham gave a tenth of the spoils.

5And indeed those who are of the sons of Levi, who receive the priesthood, have a commandment to receive tithes from the people according to the law, that is, from their brethren, though they have come from the loins of Abraham;

6but he whose genealogy is not derived from them received tithes from Abraham and blessed him who had the promises.
