2 Chronicles 24:25 Holman Christian Standard Bible (HCSB)
25 When 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 Jehoiada the priest. So he died, and they buried him in the city of David, but they did not bury him in the tombs of the kings.
