Hebrews 7:2-4

American Standard Version

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 is, King of peace; ³ without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like unto the Son of God), abideth a priest continually.

⁴ Now consider how great this man was, unto whom Abraham, the patriarch, gave a tenth out of the chief spoils.
