2 Chronicles 24:25, 26

When the Arameans withdrew, they left Joash severely wounded. His officials conspired against him for murdering the son of Jehoiada the priest, and they killed him in his bed. So he died and was buried in the City of David, but not in the tombs of the kings.

Those who conspired against him were Zabad, son of Shimeath an Ammonite woman, and Jehozabad, son of Shimrith a Moabite woman.
