Jeremiah 50:16

The agricultural cycle would end, from sowing to reaping, because of the fighting of Babylon’s enemy. The enemy soldiers would return to their own lands when they finished their job.

"Cyrus, who unified the Medo-Persian Empire and then overwhelmed Babylon (ZPEB, 1:1054-56), was careful to spare the country; so the reference (Jeremiah 50:16) must be to a later attack." [Note: Feinberg, "Jeremiah," p. 674. ZPEB stands for the Zondervan Pictorial Encyclopedia of the Bible.]
