2 Chronicles 24:25-26

251When they had departed from him (for they left him very sick), his own servants conspired against him because of the blood of the 2son of Jehoiada the priest, and murdered him on his bed. So he died, and they buried him in the city of David, but they did not bury him in the tombs of the kings.

26Now these are those who conspired against him: Zabad the son of Shimeath the Ammonitess, and Jehozabad the son of Shimrith the Moabitess.
