Albert Barnes Commentary Jeremiah 51:29

"And the land trembleth and is in pain; for the purposes of Jehovah against Babylon do stand, to make the land of Babylon a desolation, without inhabitant." — Jeremiah 51:29 (ASV)

The literal translation is:

Then the earth quaked and writhed;
For the thoughts of Yahweh against
Babel have stood fast;
To make Babel a waste without inhabitant.
