2 Chronicles 24:24-25

24Although the Aramean army came with only a few men, the Lord handed over a vast army to them because the people of Judah had abandoned the Lord, the God of their ancestors. So they executed judgment on Joash.

25When the Arameans saw that Joash had many wounds, they left him. His servants conspired against him, and killed him on his bed, because he had shed the blood of the sons of the priest Jehoiada. So he died, and they buried him in the city of David, but they did not bury him in the tombs of the kings.
