Behold the noise of the bruit is come,.... Or, "the voice of hearing" ; that is, the voice heard; the report that was made that the king of Babylon had invaded the land, and was coming up to besiege Jerusalem: "and a great commotion out of the north country"; a large army from Babylon, which lay north of Judea, which came with great noise, and caused a great trembling and shaking among the inhabitants of the land whither they were coming:to make the cities of Judah desolate, and a den of dragons; this shows that the whole paragraph is to be understood of the Jewish nation, and of their destruction.
See Gill on "Jer 9:11".
