Is it inconceivable that such sunny confidence should be suddenly clouded and followed, as in the third turn of thought (vv. 9-13), by plaintive absorption in the sad realities of present distress? The very remembrance of a brighter past may have sharpened the sense of present trouble. But it is to be noted that these complaints are prayer, not aimless, self-pitying wailing. The enumeration of miseries which begins with "Have mercy upon me, for----," has a hidden hope tinging its darkness, like the faint flush of sunrise on clouds. There is no such violent change of tone as is sometimes conceived; but the pleas of the former parts are continued in this section, which adds the psalmist's sore need to God's past and the suppliant's faith, as another reason for Jehovah's help. He begins with the effects of his trouble on himself in body and soul; thence he passes to its consequences on those around him, and finally he spreads before God its cause: plots against his life. The resemblances to Psalm vi. and to several parts of Jeremiah are unmistakable. In vv. 9, 10, the physical and mental effects of anxiety are graphically described. Sunken eyes, enfeebled soul, wasted body, are gaunt witnesses of his distress. Cares seem to him to have gnawed his very bones, so weak is he. All that he can do is to sigh. And worse than all, conscience tells him that his own sin underlies his trouble, and so he is without inward stay. The picture seems exaggerated to easy-going, prosperous people; but many a sufferer has since recognised himself in it as in a mirror, and been thankful for words which gave voice to his pained heart and cheered him with the sense of companionship in the gloom.
Vv. 11, 12, are mainly the description of the often-repeated experience of friends forsaking the troubled. "Because of all my adversaries" somewhat anticipates ver. 13 in assigning the reason for the cowardly desertion. The three phrases "neighbours," "acquaintance," and "those who see me without" indicate concentric circles of increasing diameter. The psalmist is in the middle; and round him are, first, neighbours, who pour reproach on him, because of his enemies, then the wider range of "acquaintances," afraid to have anything to do with one who has such strong and numerous foes, and remotest of all, the chance people met on the way who fly from Him, as infected and dangerous. "They all forsook Him and fled." That bitter ingredient mingles in every cup of sorrow. The meanness of human nature and the selfishness of much apparent friendship are commonplaces, but the experience of them is always as painful and astonishing, as if nobody besides had ever suffered therefrom. The roughness of structure in ver. 11 _b_, "and unto my neighbours exceedingly," seems to fit the psalmist's emotion, and does not need the emendation of "exceedingly" into "burden" (Delitzsch) or "shaking of the head" (Cheyne).
In ver. 12 the desertion is bitterly summed up, as like the oblivion that waits for the dead. The unsympathising world goes on its way, and friends find new interests and forget the broken man, who used to be so much to them, as completely as if he were in his grave, or as they do the damaged cup, flung on the rubbish heap. Ver. 13 discloses the nature of the calamity which has had these effects. Whispering slanders buzz round him; he is ringed about with causes for fear, since enemies are plotting his death. The use of the first part of the verse by Jeremiah does not require the hypothesis of his authorship of the psalm, nor of the prophet's priority to the psalmist. It is always a difficult problem to settle which of two cases of the employment of the same phrase is original and which quotation. The criteria are elastic, and the conclusion is very often arrived at in deference to preconceived ideas. But Jeremiah uses the phrase as if it were a proverb or familiar expression, and the psalmist as if it were the freshly struck coinage of his own experience.
