Hebrews 7:1-3

For this Melchizedek, the king of Salem, a priest of the Most High God, who gave Abraham his blessing, meeting him when he came back after putting the kings to death, And to whom Abraham gave a tenth part of everything which he had, being first named King of righteousness, and then in addition, King of Salem, that is to say, King of peace; Being without father or mother, or family, having no birth or end to his life, being made like the Son of God, is a priest for ever.
