Hebrews 7:1-3

Mace(i) 1 For this Melchisedec was both king of Salem, and a priest of the most high God; 'twas he who met Abraham returning from the slaughter of the kings, and blessed him: 2 to whom also Abraham gave a tenth part of the whole booty: first, being by the signification of his name king of justice, and in fact king of Salem, which is, king of peace; 3 without father, without mother, without genealogy; his days have no beginning, and his life no end; but like the son of God, he was a perpetual priest.
