Verse 1-3 — Melchizedec met Abraham when returning from the rescue of Lot. His name, "King of Righteousness," doubtless suitable to his character, marked him as a type of the Messiah and his kingdom. The name of his city signified "Peace;" and as king of peace he typified Christ, the Prince of Peace, the great Reconciler of God and man. Nothing is recorded as to the beginning or end of his life; thus he typically resembled the Son of God, whose existence is from everlasting to everlasting, who had no one that was before him, and will have no one come after him, in his priesthood. Every part of Scripture honours the great King of Righteousness and Peace, our glorious High Priest and Saviour; and the more we examine it, the more we shall be convinced, that the testimony of Jesus is the spirit of prophecy.
Verse 4-10 — That High Priest who should afterward appear, of whom Melchizedec was a type, must be much superior to the Levitical priests. Observe Abraham's great dignity and happiness; that he had the promises. That man is rich and happy indeed, who has the promises, both of the life that now is, and of that which is to come. This honour have all those who receive the Lord Jesus. Let us go forth in our spiritual conflicts, trusting in his word and strength, ascribing our victories to his grace, and desiring to be met and blessed by him in all our ways.
Verse 11-25 — The priesthood and law by which perfection could not come, are done away; a Priest is risen, and a dispensation now set up, by which true believers may be made perfect. That there is such a change is plain. The law which made the Levitical priesthood, showed that the priests were frail, dying creatures, not able to save their own lives, much less could they save the souls of those who came to them. But the High Priest of our profession holds his office by the power of endless life in himself; not only to keep himself alive, but to give spiritual and eternal life to all who rely upon his sacrifice and intercession. The better covenant, of which Jesus was the Surety, is not here contrasted with the covenant of works, by which every transgressor is shut up under the curse. It is distinguished from the Sinai covenant with Israel, and the legal dispensation under which the church so long remained. The better covenant brought the church and every believer into clearer light, more perfect liberty, and more abundant privileges. In the order of Aaron there was a multitude of priests, of high priests one after another; but in the priesthood of Christ there is only one and the same. This is the believer's safety and happiness, that this everlasting High Priest is able to save to the uttermost, in all times, in all cases. Surely then it becomes us to desire a spirituality and holiness, as much beyond those of the Old Testament believers, as our advantages exceed theirs.
Verse 26-28 — Observe the description of the personal holiness of Christ. He is free from all habits or principles of sin, not having the least disposition to it in his nature. No sin dwells in him, not the least sinful inclination, though such dwells in the best of Christians. He is harmless, free from all actual transgression; he did no violence, nor was there any deceit in his mouth. He is undefiled. It is hard to keep ourselves pure, so as not to partake the guilt of other men's sins. But none need be dismayed who come to God in the name of his beloved Son. Let them be assured that he will deliver them in the time of trial and suffering, in the time of prosperity, in the hour of death, and in the day of judgment.
