(15) Why criest thou . . .?--The personification of the previous verse is continued. The prophet looks on Judah--as in Lamentations 1:1-2--as on some forlorn and desperate castaway smitten with pestilence, crying in the agony of her hopelessness; and he reminds her that she is but bearing the righteous punishment of her iniquities. In accepting the law of retribution, as seen in her own su30:12-17 When God is against a people, who will be for them? Who can be for them, so as to do them any kindness? Incurable griefs are owing to incurable lusts. Yet, though the captives suffered justly, and could not help themselves, the Lord intended to appear for them, and to punish their oppressors; and he will still do so. But every effort to heal ourselves must prove fruitless, so long as we neglect the heavenly Advocate and sanctifying Spirit. The dealings of His grace with every true convert, and every returning backslider, are the same in effect as his proceedings to the Jews.Why criest thou for thine affliction?.... Or complainest of the hardness, and heaviness, and continuance of it, when there was such a just cause for it? when men have sinned at a high rate, they have no reason to complain of the punishment of their sins, Lamentations 3:39;

thy sorrow is incurable, for the multitude of thine iniquity; such were the number of their iniquities, that they brought them into such a sorrowful and wretched estate and condition that there was no recovery of them, nor hope of recovery of them, by their own power, or by the help and assistance of others:

because thy sins were increased I have done these things unto thee; which shows the justice of God, and is a vindication of it under all the seeming severity of it. The Jews (x) acknowledge, that under the second temple there was a great increase of capital crimes, such as murders, adulteries, &c. for which, and other sins, wrath came upon them to the uttermost by the Romans; and they still continue under the visible marks of the divine displeasure.
