2 Chronicles 24:24-25

24Although the Aramean army had come with only a few men, the LORD delivered into their hand a very great army. Because Judah had forsaken the LORD, the God of their fathers, judgment was executed on Joash.

25And when the Arameans had withdrawn, they left Joash severely wounded. His own servants conspired against him for shedding the blood of the son1 of Jehoiada the priest, and they killed him on his bed. So he died and was buried in the City of David, but not in the tombs of the kings.
