Christ’s Priesthood Typified. In a notable Messianic prophecy the sworn oath of Jehovah to David’s “Lord” is: “You are a priest to time indefinite according to the manner of Melchizedek!” (Ps 110:1, 4) This inspired psalm gave the Hebrews reason to regard the promised Messiah as the one in whom the office of priest and king would be combined. The apostle Paul, in the letter to the Hebrews, removed any doubt about the identity of the one foretold, speaking of “Jesus, who has become a high priest according to the manner of Melchizedek forever.”​—Heb 6:20; 5:10; see COVENANT.

The fact remains that Melchizedek’s nationality, genealogy, and offspring are left undisclosed in the Scriptures, and that with good reason, for he could thus typify Jesus Christ, who by Jehovah’s sworn oath “has become a high priest according to the manner of Melchizedek forever.”​—Heb 6:20.
