Hebräer 7:8

Second point of superiority: Melchisedec's is an enduring, the Levitical a transitory, priesthood. As the law was a parenthesis between Abraham's dispensation of promise of grace, and its enduring fulfilment at Christ's coming (Rom 5:20, Greek, "The law entered as something adscititious and by the way"): so the Levitical priesthood was parenthetical and temporary, between Melchisedec's typically enduring priesthood, and its antitypical realization in our ever continuing High Priest, Christ. here--in the Levitical priesthood. there--in the priesthood after the order of Melchisedec. In order to bring out the typical parallel more strongly, Paul substitutes, "He of whom it is witnessed that he liveth," for the more untypical, "He who is made like to Him that liveth." Melchisedec "liveth" merely in his official capacity, his priesthood being continued in Christ. Christ, on the other hand, is, in His own person, "ever living after the power of an endless life" (Heb 7:16, Heb 7:25). Melchisedec's death not being recorded, is expressed by the positive term "liveth," for the sake of bringing into prominence the antitype, Christ, of whom alone it is strictly and perfectly true, "that He liveth."

The doctrine of the priestly office of Christ is so excellent in itself, and so essential a part of the Christian faith, that the apostle loves to dwell upon it. Nothing made the Jews so fond of the Levitical dispensation as the high esteem they had of their priesthood, and it was doubtless a sacred and most excellent institution; it was a very severe threatening denounced against the Jews (Hos 3:4), that the children of Israel should abide many days without a prince or priest, and without a sacrifice, and with an ephod, and without teraphim. Now the apostle assures them that by receiving the Lord Jesus they would have a much better high priest, a priesthood of a higher order, and consequently a better dispensation or covenant, a better law and testament; this he shows in this chapter, where, I. We have a more particular account of Melchisedec (Heb 7:1-3). II. The superiority of his priesthood to that of Aaron (Heb 7:4-10). III. An accommodation of all to Christ, to show the superior excellency of his person, office, and covenant (Heb 7:11 to the end).

7:8 Melchizedek’s “immortality” (7:3) is one aspect of his superiority to the Levites: The Levites are men who die, but Melchizedek lives on.
