2 Chronicles 25:28

Amaziah the son of Joash, king of Judah, lived for fifteen years after the death of Joash, son of Jehoahaz, king of Israel.

Now the rest of the acts of Amaziah, first and last, behold, aren’t they written in the book of the kings of Judah and Israel?

Now from the time that Amaziah turned away from following the LORD, they made a conspiracy against him in Jerusalem. He fled to Lachish, but they sent after him to Lachish and killed him there.
