Lamentations 1:12

The complaints here are, for substance, the same with those in the foregoing part of the chapter; but in these verses the prophet, in the name of the lamenting church, does more particularly acknowledge the hand of god in these calamities, and the righteousness of his hand. I. The church in distress here magnifies her affliction, and yet no more than there was cause for; her groaning was not heavier than her strokes. She appeals to all spectators: See if there be any sorrow like unto my sorrow, Lam 1:12. This might perhaps be truly said of Jerusalem's griefs; but we are apt to apply it too sensibly to ourselves when we are in trouble and more than there is cause for. Because we feel most from our own burden, and cannot be persuaded to reconcile ourselves to it, we are ready to cry out, Surely never was sorrow like unto our sorrow; whereas, if our troubles were to be thrown into a common stock with those of others, and then an equal dividend made, share and share alike, rather than stand to that we should each of us say, "Pray, give me my own again." II.

The pathetic appeal of Jerusalem, not only to her neighbors, but even to the strangers "passing by," as her sorrow is such as should excite the compassion even of those unconnected with her. She here prefigures Christ, whom the language is prophetically made to suit, more than Jerusalem. Compare Israel, that is, Messiah, Isa 49:3. Compare with "pass by," Mat 27:39; Mar 15:29. As to Jerusalem, Dan 9:12. M AURER, from the Arabic idiom, translates, "do not go off on your way," that is, stop, whoever ye are that pass by. English Version is simpler.
