Hebrews 7:6

he whose descent is not counted from them--not from "the sons of Levi," as those "who receive the priesthood." This verse explains "without descent" (Greek, "genealogy" in both verses, Heb 7:3). He who needs not, as the Levitical priests, to be able to trace his genealogy back to Levi. received--Greek, "hath received tithes." blessed--Greek, "hath blessed." The perfect tense implies that the significance of the fact endures to the present time. him that had--"the possessor of the promises," Abraham's peculiar distinction and designation. Paul exalts Abraham in order still more to exalt Melchisedec. When Christ is the subject, the singular "promise" is used. "The promises" in the plural, refer to God's promise of greatness to himself and his seed, and of the possession of Canaan, twice repeated before the blessing of Melchisedec. As the priests, though above the people (Heb 7:7) whom it was their duty to "bless," were yet subordinate to Abraham; and as Abraham was subordinate to Melchisedec, who blessed him, Melchisedec must be much above the Levitical priests.

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).

7:6b-7 Melchizedek placed a blessing upon Abraham: Gen 14:19-20; this is an example of the kind of blessing that a superior would give a subordinate—e.g., a father would bless his son, and a priest would bless his people (Gen 49:1-28; Num 6:22-27). The power to give a blessing demonstrates that Melchizedek is greater than Abraham.
