Hebrews 7:1-10 - The Greatness Of Melchizedek
1 For this Melchizedek, king of Salem, priest of the most high God, who met Abraham [as he] was returning from the slaughter of the kings and blessed him, 2 to whom also Abraham apportioned a tenth of everything--in the first place, [his name] is translated "king of righteousness," and then also "king of Salem," that is, "king of peace"; 3 without father, without mother, without genealogy, having neither beginning of days nor end of life, but resembling the Son of God--he remains a priest for all time.
4 But see how great this man [was], to whom Abraham the patriarch gave a tenth from the spoils! 5 And indeed those of the sons of Levi who receive the priesthood have a commandment to collect a tenth from the people according to the law, that is, from their brothers, although {they are descended from Abraham}. 6 But the one who did not trace [his] descent from them collected tithes from Abraham and blessed the one who had the promises. 7 Now without any dispute the inferior is blessed by the more prominent. 8 And in this case mortal men receive tithes, but in that case it is testified that he lives. 9 And, {so to speak}, even Levi, the one who receives tithes, has paid tithes through Abraham. 10 For he was still in the loins of his father when Melchizedek met him.
