Jeremiah 34:7 Meaning and Commentary

Jeremiah 34:7

When the king of Babylon's army fought against Jerusalem
Had laid close siege to it, and still continued it: and against all the cities of Judah that were left;
unconquered by him; when he invaded the land, he fought against, and took, and ravished all the cities that lay in his way; and it seems there were none that stood out against him but Jerusalem, now besieged by him, and two others, next mentioned: against Lachish, and against Azekah; for these defenced cities
remained of the cities of Judah;
two cities that had been fortified by Rehoboam, ( 2 Chronicles 11:9 ) ; and were the only ones besides Jerusalem, which as yet had not fallen into the hands of the king of Babylon.
