12 'Then it will come to pass, when seventy years are completed, that I will punish the king of Babylon and that nation, the land of the Chaldeans, for their iniquity,' says the Lord; 'and I will make it a perpetual desolation. 13 So I will bring on that land all My words which I have pronounced against it, all that is written in this book, which Jeremiah has prophesied concerning all the nations. 14 (For many nations and great kings shall be served by them also; and I will repay them according to their deeds and according to the works of their own hands.)' "
Matthew Henry's Commentary on Jeremiah 25:12-14
Commentary on Jeremiah 25:8-14
(Read Jeremiah 25:8-14)
The fixing of the time during which the Jewish captivity should last, would not only confirm the prophecy, but also comfort the people of God, and encourage faith and prayer. The ruin of Babylon is foretold: the rod will be thrown into the fire when the correcting work is done. When the set time to favour Zion is come, Babylon shall be punished for their iniquity, as other nations have been punished for their sins. Every threatening of the Scripture will certainly be accomplished.
