The International Standard Bible Encyclopedia (ISBE) comments: "The argument of Hebrews 7 is similar to the rabbinic argument from silence, which assumed that nothing exists unless Scripture mentions it. Since Genesis says nothing of Melchizedek's parents, genealogy, birth, or death, he serves as a type representing the eternal Son of God (v. 3)" ("Melchizedek," vol. 3, p. 313).
