Jeremiah 51:52

The design of the Prophet is, as I have reminded you, to raise up the minds of the godly that they might not succumb under their trials, on seeing that they were exposed to shame and were destitute of all honors. He then says that the time would come when God would take vengeance on the idols of Babylon. And thus God claims for himself that power which seemed then to have almost disappeared; for the temple being overthrown, the Babylonians seemed in a manner to triumph over him, as God’s power in the temple was overcome. Then as the ruin of it, as we have said, seemed to have extinguished God’s power, the Prophet applies a remedy, and says that though the temple was overthrown, yet God remained perfect and his power unchangeable. But among other things he bids the faithful patiently to wait, for he invites their attention to the hope of what was as yet hidden.

But he says, “the days will come;” by these words he reminds us that we are to cherish the hope of the promises until God completes his work; and thus he corrected that ardor by which we are seized in the midst of our afflictions, for we wish immediately to fly away to God. The Prophet, then, here exhorts the faithful to sustain courage until the time fixed by God; and so he refers them to God’s providence, lest they assumed too much in wishing him to act as their own minds led them. Come then shall the days when I shall visit the graven images of Babylon; and groan or cry, etc.; for the word אנק , anak, means to cry. Some render thus, “groan shall the wounded;” and they render the last word “wounded,” because they think it improper to say that the slain cry or groan. But the Prophet means that the cry in that slaughter would be great, that is, that while the Babylonians were slain, a great howling would be everywhere. It follows, —
