2 Kings 14:11-15

But Amaziah would not listen. So Jehoash king of Israel went up; and they faced each other, he and Amaziah king of Judah, at Beth-shemesh, which belongs to Judah.

And Judah was defeated by Israel, and they fled, every man to his tent.

Then Jehoash king of Israel captured Amaziah king of Judah, the son of Jehoash the son of Ahaziah, at Beth-shemesh, and came to Jerusalem and tore down the wall of Jerusalem from the Gate of Ephraim to the Corner Gate, four hundred cubits.

And he took all the gold and silver and all the utensils which were found in the house of the Lord, and in the treasuries of the king’s house, the hostages as well, and returned to Samaria. Jeroboam II Succeeds Jehoash (Joash) in Israel

Now as for the rest of the acts of Jehoash that he did, and his might and how he fought with Amaziah king of Judah, are they not written in the Book of the Chronicles of the Kings of Israel?
