The psalm may be regarded as divided into three parts, in each of which a different phase of agitated feeling predominates, but not exclusively. Strong excitement does not marshal emotions or their expression according to artistic proprieties of sequence, and this psalm is all ablaze with it. That vehemence of emotion sufficiently accounts for both the occasional obscurities and the manifest want of strict accuracy in the flow of thought, without the assumption of dislocation of parts or piecing it with a fragment of another psalm. When the heart is writhing within, and tumultuous feelings are knocking at the door of the lips, the words will be troubled and heaped together, and dominant thoughts will repeat themselves in defiance of logical continuity. But, still, complaint and longing sound through the waning, yearning notes of vv. 1-8; hot indignation and terrible imprecations in the stormy central portion (vv. 9-15); and a calmer note of confidence and hope, through which, however, the former indignation surges up again, is audible in the closing verses (vv. 16-23).
The psalmist pictures his emotions in the first part, with but one reference to their cause, and but one verse of petition. He begins, indeed, with asking that his prayer may be heard; and it is well when a troubled heart can raise itself above the sea of troubles to stretch a hand towards God. Such an effort of faith already prophesies firm footing on the safe shore. But very pathetic and true to the experience of many a sorrowing heart is the psalmist's immediately subsequent dilating on his griefs. There is a dumb sorrow, and there is one which unpacks its heart in many words and knows not when to stop. The psalmist is _distracted_ in his bitter brooding on his troubles. The word means to move restlessly, and may either apply to body or mind, perhaps to both; for Eastern demonstrativeness is not paralysed, but stimulated to bodily tokens, by sorrow. He can do nothing but groan or moan. His heart "writhes" in him. Like an avalanche, deadly terrors have fallen on him and crushed him. Fear and trembling have pierced into his inner being, and "horror" (a rare word, which the LXX. here renders _darkness_) wraps him round or covers him, as a cloak does. It is not so much the pressure of present evil, as the shuddering anticipation of a heavier storm about to burst, which is indicated by these pathetic expressions. The cause of them is stated in a single verse (3). "The voice of the enemy" rather than his hand is mentioned first, since threats and reproaches precede assaults; and it is budding, not full-blown, enmity which is in view. In ver. 3 _b_ "oppression" is an imperfect parallelism with "voice," and the conjectural emendation (which only requires the prefixing of a letter) of "cries," adopted by Cheyne, after Olshausen and others, is tempting. They "fling down iniquity" on him as rocks are hurled or rolled from a height on invaders--a phrase which recalls David's words to his servants, urging flight before Absalom, "lest he bring down evil upon us."
Then, from out of all this plaintive description of the psalmist's agitation and its causes, starts up that immortal strain which answers to the deepest longings of the soul, and has touched responsive chords in all whose lives are not hopelessly outward and superficial--the yearning for repose. It may be ignoble, or lofty and pure; it may mean only cowardice or indolence; but it is deepest in those who stand most unflinchingly at their posts, and crush it down at the command of duty. Unless a soul knows that yearning for a home in stillness, "afar from the sphere of our sorrow," it will remain a stranger to many high and noble things. The psalmist was moved to utter this longing by his painful consciousness of encompassing evils; but the longing is more than a desire for exemption from these. It is the cry of the homeless soul, which, like the dove from the ark, finds no resting-place in a world full of carrion, and would fain return whence it came. "O God, Thou hast made us for Thyself, and we are unquiet till we find rest in Thee." No obligation of duty keeps migratory birds in a land where winter is near. But men are better than birds, because they have other things to think of than repose, and must face, not flee, storms and hurricanes. It is better to have wings "like birds of tempest-loving kind," and to beat up against the wind, than to outfly it in retreat. So the psalmist's wish was but a wish; and he, like the rest of us, had to stand to his post, or be tied to his stake, and let enemies and storms do their worst. The LXX. has a striking reading of ver. 8, which Cheyne has partially adopted. It reads for ver. 8 _a_ "waiting for Him who saves me"; but beautiful as this is, as giving the picture of the restful fugitive in patient expectation, it brings an entirely new idea into the picture, and blends metaphor and fact confusedly. The Selah at the close of ver. 7 deepens the sense of still repose by a prolonged instrumental interlude.
