2 Chronicles 24:25-26

25When the Arameans withdrew, they left him suffering from many wounds. His own officials plotted against him for murdering the son of the priest Jehoiada. They killed Joash in his bed. When he died, they buried him in the City of David, but they didn’t bury him in the tombs of the kings.

26These were the men who conspired against him: Zabad, son of an Ammonite woman named Shimeath, and Jehozabad, son of a Moabite woman named Shimrith.
