John Gill Commentary Jeremiah 25:11

"And this whole land shall be a desolation, and an astonishment; and these nations shall serve the king of Babylon seventy years." — Jeremiah 25:11 (ASV)

And this whole land shall be a desolation

Not only the city of Jerusalem, but all Judea, without inhabitants, or very few, and shall be uncultivated, and become barren and unfruitful.

[and] an astonishment

to all other nations, and to all persons that pass through, beholding the desolations of it.

and other nations shall serve the king of Babylon seventy years

both the Jews, and other nations of Egypt, reckoning from the date of this prophecy, the fourth year of Jehoiakim's reign, when Daniel and others were carried captive, (Daniel 1:1–6) ; to the first year of Cyrus.
