Hebrews 7:1-3

7:1 For this Melchizedek, king of Salem, priest of God Most High, who met Abraham returning from the slaughter of the kings and blessed him,

7:2 to whom also Abraham divided a tenth part of all (being first, by interpretation, “king of righteousness”, and then also “king of Salem”, which means “king of peace”,

7:3 without 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.
