There may be deep meaning in the slight omission of "greatly" in the second refrain. Confidence has grown. The first hope was that the waiting heart should not be much shaken, that the tottering fence should not be quite thrown down; the second is that it shall not be shaken at all. An access of faith has poured into the singer's soul with his song; and now he has no thought of the crowd of assailants, who have faded from his sight because he is gazing on God. Hence the second pair of verses in this strophe (vv. 7, 8) substitutes for the description of their fierce rush the triumphant reiteration of what God is to the psalmist, and an invitation to others to come with him into that strong refuge. The transition to addressing the "people" is natural, if the psalm is David's. The phrase would then apply to his immediate followers, who were one with him in peril, and whom he would fain have one with him in trust. But the LXX. has another reading, which involves only the insertion of a letter, that may easily have dropped out, in the word rendered "time," and which makes the verse run more smoothly. It reads "all the congregation of the people," in which it is followed by Baethgen, Cheyne, and others. Whoever the psalmist was, he felt the impulse which follows all deep experience of the security that comes from hiding in God--namely, the longing to beckon in others out of the storm into peace. Every man who has learned that God is a refuge for him is thereby assured that He is the same for all men, and thereby moved to beseech them to make the like blessed discovery. The way into that hiding-place is trust. "Pour out before Him your heart," says the psalmist. "In everything by prayer and supplication with thanksgiving let your requests be made known unto God," says Paul. They both mean the same thing. We take refuge in our refuge when we set our faith on God, and tell Him all that threatens or troubles us. When we do, we are no longer in the open, defenceless before the rush of enemies, but housed in God, or, as Paul puts it, guarded in Christ Jesus, as in a fortress. No wonder that the psalm pauses for a moment on that thought, and lets the notes of harp and horn impress it on the listeners!
The third strophe sets the emptiness of men in strong contrast to the sufficiency of God. "Vanity" is literally "a breath," and would better be so rendered in ver. 9, but for the recurrence of the verb from the same root in ver. 10, which requires the rendering "be not vain." It is desirable to preserve identity of translation, so as to retain the play of words. But by doing so ver. 9 is somewhat weakened. The eyes that have been looking on God are cleared to see the shadowy nothingness of men of all degrees. The differences of high and low dwindle when seen from that "high tower," as lower lands appear flat when viewed from a mountain top. They are but "breath," so fleeting, unsubstantial are they. They are a "lie," in so far as hopes directed to them are deceived and trust misplaced. The singer is not cynically proclaiming man's worthlessness, but asserting his insufficiency as the object of man's trust. His point of view is different from that of Psalm xxxix., though his words are the same. The "Only" which begins ver. 9 carries us back to the similar beginning of the preceding strophes, and brings out the true force of the following words, by suggesting the contrast between men and the God on whom the psalmist's soul waits in silence. That contrast may be further continued in ver. 9 _b_. The lowly and the lofty are in one scale. What is in the other, the solid weight of which sends them aloft as lighter? Is it pressing the metaphor too far to suppose that the psalmist is weighing the whole mass of men against God only? Heap them altogether and balance them against Him, and the gathered mass does not weigh as much as an imponderable breath. Who could trust in that emptiness when he has God to trust in? Who would grasp shadows when he may cling to that eternal Substance?
