John Gill Commentary Jeremiah 50:22

"A sound of battle is in the land, and of great destruction." — Jeremiah 50:22 (ASV)

A sound of battle [is] in the land
In the land of the Chaldeans, as it is expressed in the Septuagint and Arabic versions; the noise of warriors, the clashing of arms, and sound of trumpets, both of the enemy entered into the land, and of the Chaldeans arming themselves in their own defence: and of great destruction ;
in the same land; or in Babylon, as Abarbinel supplies it; this is the consequent of the former.
