7:1-3 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.

2. gave—Greek, "apportioned"; assigned as his portion.

tenth … of all—namely, the booty taken. The tithes given are closely associated with the priesthood: the mediating priest received them as a pledge of the giver's whole property being God's; and as he conveyed God's gifts to man (Heb 7:1, "blessed him"), so also man's gifts to God. Melchisedec is a sample of how God preserves, amidst general apostasy, an elect remnant. The meeting of Melchisedec and Abraham is the connecting link between to two dispensations, the patriarchal, represented by Melchisedec, who seems to have been specially consecrated by God as a KING-PRIEST, the highest form of that primitive system in which each father of a household was priest in it, and the Levitical, represented by Abraham, in which the priesthood was to be limited to one family of one tribe and one nation. The Levitical was parenthetical, and severed the kingdom and priesthood; the patriarchal was the true forerunner of Christ's, which, like Melchisedec's, unites the kingship and priesthood, and is not derived from other man, or transmitted to other man; but derived from God, and is transmitted in God to a never-ending perpetuity. Melchisedec's priesthood continueth in Christ for ever. For other points of superiority, see Heb 7:16-21. Melchisedec must have had some special consecration above the other patriarchs, as Abraham, who also exercised the priesthood; else Abraham would not have paid tithe to him as to a superior. His peculiar function seems to have been, by God's special call, KING-priest whereas no other "patriarch-priest" was also a God-consecrated king.

first being—Paul begins the mystical explanation of the historical fact (allegorical explanations being familiar to JEWS), by mentioning the significancy of the name.

righteousness—not merely righteous: so Christ. Hebrew "Malchi" means king: "Tzedek," righteousness.

King of Salem—not only his own name, but that of the city which he ruled, had a typical significance, namely, peace. Christ is the true Prince of peace. The peace which He brings is the fruit of righteousness.
