2 Chronicles 24:24-25

24 For the army of the Syrians came with a small company of men, and the LORD delivered a very great host into their hand, because they had forsaken the LORD God of their fathers. So they executed judgment against Joash.
25 And when they were departed from him, (for they left him in great diseases,) his own servants conspired against him for the blood of the sons of Jehoiada the priest, and slew him on his bed, and he died: and they buried him in the city of David, but they buried him not in the sepulchres of the kings.
