John Calvin's Bible Commentary
Lamentations 2:5
These words might seem superfluous, since the Prophet has often repeated, that God was become an enemy to his own people; but we shall hereafter see, that though they were extremely afflicted, they yet did not rightly consider whence their calamity arose. As, then, they had become so stupified by their evils, that they did not turn their eyes to God, they were on this account often urged and stimulated, that they might at length understand by their evils that God was a judge. Now, as it was difficult to convince them of this truth, the Prophet did not think it enough briefly to touch on it, but found it necessary to dwell on it at large, so that the people might at length be roused from their insensibility.
