isaiah 39:6 Behold, the days come, that all that is in thine house, and that which thy fathers have laid up in store until this day, shall be carried to Babylon: nothing shall be left, saith the LORD. - Free Bible Online

      6. days come--one hundred twenty years afterwards. This is the first intimation that the Jews would be carried to Babylon--the first designation of their place of punishment. The general prophecy of Moses (Le 26:33; De 28:64); the more particular one of Ahijah in Jeroboam's time (1Ki 14:15), "beyond the river"; and of Am 5:27, "captivity beyond Damascus"; are now concentrated in this specific one as to "Babylon" (Mic 4:10). It was an exact retribution in kind, that as Babylon had been the instrument of Hezekiah and Judah's sin, so also it should be the instrument of their punishment.
