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.
