And the full-toned answer portrays the men who shall dwell with God, in words which begin indeed with stringent demands for absolute purity, but wonderfully change in tone as they advance, into gracious assurances, and the clearest vision that the moral nature which fits for God's presence is God's gift. "The clean-handed, and pure-hearted, who has not lifted up his soul to vanity, nor sworn deceitfully;" there is the eternal law which nothing can ever alter, that to abide with God a man must be like God—the law of the new covenant as of the old, "Blessed are the pure in heart, for they shall see God." But this requirement, impossible of fulfilment, is not all. If it were, the climbing procession might stop. But up and up they rise, and once again the song bursts forth in deeper and more hopeful words, "He shall receive the blessing from Jehovah, and righteousness from the God of his salvation."
Then that righteousness, which he who honestly attempts to comply with such requirements will soon find that he does not possess, is to be received from above, not elaborated from within; is a gift from God, not a product of man's toils. God will make us pure, that we may dwell with Him. Nor is this all. The condition of receiving such a gift has been already partially set forth in the preceding clause, which seems to require righteousness to be possessed as the preliminary to receiving it. The paradox which thus results is inseparable from the stage of religious knowledge attained under the Mosaic Law. But the last words of the answer go far beyond it, and proclaim the special truth of the gospel, that the righteousness which fits for dwelling with God is given on the simple condition of seeking Him. To this designation of the true worshippers is appended somewhat abruptly the one word "Jacob," which need neither be rendered as in the English version as an invocation, nor as in the margin, with an unnecessary and improbable supplement, "O God of Jacob;" but is best regarded as in apposition with the other descriptive clauses, and declaring, as we have found David doing already in previous psalms, that the characters portrayed in them, and these only, constituted the true Israel.
And so the first question is answered, "Who are the men who dwell with God?"—The pure, who receive righteousness, who seek Him, the true Israel.
And now the procession has reached the front of the ancient city on the hill, and stands before the very walls and weather-beaten gates which Melchizedek may have passed through, and which had been barred against Israel till David's might had burst them. National triumph and glad worship are wonderfully blended in the summons which rings from the lips of the Levites without: "Lift up your heads, O ye gates! and be ye lift up, ye doors (that have been from) of old!" as if even their towering portals were too low, "and the King of glory shall come in." What force in that name here, in this early song of the King! How clearly he recognises his own derived power, and the real Monarch of whom he is but the shadowy representative!
The newly-conquered city is summoned to admit its true conqueror and sovereign, whose throne is the ark, which was emphatically named "the glory," and in whose train the earthly king follows as a subject and a worshipper. Then, with wonderful dramatic force, a single voice from within the barred gates asks, like some suspicious warder, "Who then is the King of glory?" With what a shout of proud confidence and triumphant memories of a hundred fields comes, ready and full, the crash of many voices in the answer, "Jehovah strong and mighty, Jehovah mighty in battle!" How vividly the reluctance of an antagonistic world to yield to Israel and Israel's King, is represented in the repetition of the question in a form slightly more expressive of ignorance and doubt, in answer to the reiterated summons, "Who is He, then, the King of glory?" With what deepened intensity of triumph there peals, hoarse and deep, the choral shout, "The Lord of Hosts, He is the King of glory." That name which sets Him forth as Sovereign of the personal and impersonal forces of the universe—angels, and stars, and terrene creatures, all gathered in ordered ranks, embattled for His service—was a comparatively new name in Israel, and brought with it thoughts of irresistible might in earth and heaven. It crashes like a catapult against the ancient gates; and at that proclamation of the omnipotent name of the God who dwells with men, they grate back on their brazen hinges, and the ark of the Lord enters into its rest.
