Remembering how the holy chrism had faded from the raven locks of Saul long before his bloody head had been sent round Philistine cities to glut their revenge, and knowing that if God were "strict to mark iniquity," the gift which had been withdrawn from Saul would not be continued to himself, he prays, not as anointed monarch only, but as sinful man, "Take not Thy Holy Spirit from me." As before he had ventured to ask for the joy of forgiveness, so now he pleads once more for "the joy of Thy salvation," which comes from cleansing, from conscious fellowship—which he had so long and deeply felt, which for so many months had been hid from him by the mists of his own sin. The psalmist's natural buoyancy, the gladness which was an inseparable part of his religion, and had rung from his harp in many an hour of peril, the bold width of his desires, grounded on the clear breadth of his faith in God's perfect forgiveness, are all expressed in such a prayer from such lips at such a time, and may well be pondered and imitated by us.
The lowly prayer which we have been tracing rises ere its close to a vow of renewed praise. It is very beautiful to note how the poet nature, as well as the consciousness of a Divine function, unite in the resolve that crowns the psalm. To David no tribute that he could bring to God seemed so little unworthy—none to himself so joyous—as the music of his harp, and the melody of his songs; nor was any part of his kingly office so lofty in his estimation as his calling to proclaim in glowing words the name of the Lord, that men might learn to love. His earliest song in exile had closed with a like vow. It had been well fulfilled for many a year; but these last doleful months had silenced all his praise. Now, as hope begins to shine upon him once more, the frost which had stilled the stream of his devotion is melting, and as he remembers his glad songs of old, and this miserable dumbness, his final prayer is, "O Lord, open Thou my lips, and my mouth shall show forth Thy praise."
The same consciousness of sin, which we have found in a previous verse discerning the true significance of ceremonial purification, leads also to the recognition of the insufficiency of outward sacrifices—a thought which is not, as some modern critics would fain make it, the product of the latest age of Judaism, but appears occasionally through the whole of the history, and indicates not the date, but the spiritual elevation of its utterer. David sets it on the very summit of his psalm, to sparkle there like some stone of price. The rich jewel which he has brought up from the abyss of degradation is that truth which has shone out from its setting here over three millenniums: "The sacrifices of God are a broken spirit; a broken and a contrite heart, O God, Thou wilt not despise."
The words which follow, containing a prayer for the building up of Zion, and a prediction of the continuous offering of sacrifice, present some difficulty. They do not necessarily presuppose that Jerusalem is in ruins; for "build Thou the walls" would be no less appropriate a petition if the fortifications were unfinished (as we know they were in David's time) than if they had been broken down. Nor do the words contradict the view of sacrifice just given, for the use of the symbol and the conviction of its insufficiency co-existed, in fact, in every devout life, and may well be expressed side by side. But the transition from so intensely personal emotions to intercession for Zion seems almost too sudden even for a nature as wide and warm as David's. If the closing verses are his, we may, indeed, see in them the king re-awaking to a sense of his responsibilities, which he had so long neglected, first, in the selfishness of his heart, and then in the morbid self-absorption of his remorse; and the lesson may be a precious one that the first thought of a pardoned man should be for others.
But there is much to be said, on the other hand, in favour of the conjecture that these verses are a later addition, probably after the return from captivity, when the walls of Zion were in ruins, and the altar of the temple had been long cold. If so, then our psalm, as it came from David's full heart, would be all of a piece—one great gush of penitence and faith, beginning with, "Have mercy upon me, O God," ending with the assurance of acceptance, and so remaining for all ages the chart of the thorny and yet blessed path that leads "from death unto life." In that aspect, what it does not contain is as noteworthy as what it does. Not one word asks for exemption from such penalties of his great fall as can be inflicted by a loving Father on a soul that lives in His love. He cries for pardon, but he gives his back to the smiters whom God may please to send.
