11 This whole land shall be a desolation, and an astonishment; and these nations shall serve the king of Babylon seventy years. 12 It shall happen, when seventy years are accomplished, that I will punish the king of Babylon, and that nation, says Yahweh, for their iniquity, and the land of the Chaldeans; and I will make it desolate forever.
Matthew Henry's Commentary on Jeremiah 25:11-12
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.
