And he shall have it, and his seed after him. — The covenant of peace, which was made by the blood of the Cross, and all the blessings which belong to that covenant, stand fast with Christ, and are secured to His spiritual seed. (Comp. Psalms 89:28-29.)
Even the covenant of an everlasting priesthood. — Phinehas succeeded his father Eleazar as high priest (Judges 20:28). After a temporary interruption in the succession, which existed in the time of Eli, and continued until the time of David, when there appears to have been a joint high-priesthood, the office was restored by Solomon to Zadok, the descendant of Phinehas, and so continued until the gradual dissolution of the Jewish state. Christ’s priesthood is “an unchangeable priesthood” (Hebrews 7:24): “Thou art a priest for ever after the order of Melchisedec” (Hebrews 7:17).
