The psalmist's silence finds voice, which does not break it, in saying over to himself what God is to him. His accumulation of epithets reminds us of Psalm xviii. 1, 2. Not only does his salvation come from God, but God Himself is the salvation which He sends forth like an angel. The recognition of God as his defence is the ground of "silence"; for if He is "my rock and my salvation," what can be wiser than to keep close to Him, and let Him do as He will? The assurance of personal safety is inseparable from such a thought of God. Nothing which does not shake the rock can shake the frail tent pitched on it. As long as the tower stands, its inhabitant can look down from his inaccessible fastness with equanimity, though assailed by crowds. Thus the psalmist turns swiftly, in the latter pair of verses making up the first strophe, to address remonstrances to his enemies, as engaged in a useless effort, and then drops direct address and speaks _of_ their hostility and treachery. The precise meaning of parts of ver. 3 has been misapprehended, by reason of the peculiarities of some of the words and the condensed character of the imagery in _b_, _c_. The rendering above is substantially that generally accepted now. It sets in striking contrast the single figure of the psalmist and the multitude of his assailants. "All of you" rush upon a man like a pack of hounds on one defenceless creature, and try to break him down, as men put their shoulders to a wall in order to overthrow it. The partial success of the assault is hinted in the epithets applied to wall and fence, which are painted as beginning to give under pressure. Language of confidence sounds strangely in such circumstances. But the toppling wall, with all these strong men pushing at it, will "not be greatly moved." The assailants might answer the psalmist's "How long?" with defiant confidence that a short time only was needed to complete the begun ruin; but he, firm in his faith, though tottering in his fortunes, knows better, and, in effect, tells them by his question that, however long they may press against his feebleness, they will never overthrow him. The bulging wall outlasts its would-be destroyers. But appeal to them is vain; for they have one settled purpose absorbing them--namely, to cast him down from his height. He is, then, probably in some position of distinction, threatened by false friends, who are plotting his deposition, while their words are fair. All these circumstances agree well with the Davidic authorship.
The second strophe reiterates the refrain, with slight but significant variations, and substitutes for the address to and contemplation of the plotters a meditation on the psalmist's own security, and an invitation to others to share it. In ver. 5 the refrain is changed from a declaration of the psalmist's silent waiting to self-exhortation thereto. Cheyne would assimilate the two verses by making both verbs imperatives; but that change destroys the beautiful play of feeling, so true to experience, which passes from consciousness of one's attitude towards God to effort at preserving it. No emotions, however blessed, deep, and real, will last, unless perpetually renewed. Like carbon points in electric lights, they burn away as they burn, and the light dies, unless there is some impulse which presses a fresh surface forward to receive the fiery kiss that changes its blackness into radiance. The "expectation" in ver. 5 _b_ is substantially equivalent to the "salvation" in ver. 1 _b_. It means not the emotion (which could not be said to be "from Him"), but the thing expected, just as "hope" is used for the _res sperata_. The change in expression from "salvation" to "expectation" makes prominent the psalmist's attitude. In his silence his wistful eyes look up, watching for the first far-off brightening which tells him that help is on its road from the throne. Salvation will not come unexpected, and expectation will not look for succours in vain.
