The army which Amaziah sent back, fell upon the cities of Judah Thus God chastised those cities of Judah for their idolatries, which were found most in the parts next to Israel. The men of Israel had corrupted them, and now are a plague to them. And thus Amaziah also was punished for having entered into an alliance with idolaters, though at the prophet's reproof he broke it off: and perhaps, likewise, this calamity befell his subjects, because he had used his victory over the Edomites with so much cruelty.
