Chronicles II 17:10 Meaning and Commentary

2 Chronicles 17:10

And the fear of the Lord fell upon all the kingdoms of the
lands that were round about Judah
Upon the ten tribes, and on foreign nations about them, as Moabites, Edomites, Syrians, Egyptians, Arabs, and Philistines; this fear, as it came from the Lord, so might be raised and increased by observing, that religion was revived in them; for they might perceive, by former observations made, that the more religious these people were, the more prosperous and formidable they were:

so that they made no war against Jehoshaphat;
to interrupt him in the work of reformation he was so intent upon.
