For this put on sackcloth, lament and wail, for the fierce anger of the LORD has not turned back from us.”
The Prophet seems not yet to exhort his own nation to repent: a more gracious doctrine will presently follow; but here he only reminds them that a most grievous mourning was nigh at hand; for he saw that they were hypocrites, immersed in their own delusions, and could not be assailed by any fear.
God's usual method is to warn before he wounds. In these verses, accordingly, God gives notice to the Jews of the general desolation that would shortly be brought upon them by a foreign invasion. This must be declared and published in all the cities of Judah and streets of Jerusalem, that all might hear and fear, and by this loud alarm be either brought to repentance or left inexcusable.
Commenting on Jeremiah 4:5-18
For this gird you with sackcloth, lament and howl,.... That is, because of this destruction threatened, which was so near at hand, and so sure and certain: for the fierce anger of the Lord is not turned back from us. The Septuagint, Syriac, and Arabic versions, render it "from you" and some render it "from it" (u); from his purpose and design to destroy the Jews.
