Albert Barnes Commentary 2 Kings 14:1

"In the second year of Joash son of Joahaz king of Israel began Amaziah the son of Joash king of Judah to reign." — 2 Kings 14:1 (ASV)

The history of Judah is resumed in 2 Kings 14:1–22, followed by a brief account of the contemporary history of Israel under Jeroboam II in 2 Kings 14:23–29. The earlier narrative runs parallel with 2 Chronicles 25.
