2 Kings 14:11

But Amaziah would not hear. Therefore Jehoash king of Israel went up; and he and Amaziah king of Judah looked one another in the face at Beth-she'mesh, which belongeth to Judah.

But Amaziah would not hear. The sarcastic tenor of this reply incited the king of Judah the more; for, being in a state of judicial blindness and infatuation (2 Chronicles 25:20), he was immovably determined on war. The superior energy of Joash, however, surprised him ere he had completed his military preparations. Pouring a numerous army into the territory of Judah, he encountered Amaziah in a pitched battle, routed his army, took himself prisoner, and having marched to Jerusalem, not only demolished part of the city walls, but plundered the treasures of the palace and temple, and, taking hostages to prevent any further molestation from Judah, terminated the war. Without leaving a garrison in Jerusalem, he returned to his capital with all convenient speed, his presence and whole forces being required to repel the troublesome incursions of the Syrians.
