2 Chronicles 24:25-29

When they left him (for they left him very sick), his own servants conspired against him because of the blood of the son of Jehoiada the priest, and they 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.

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

As to his sons and the many pronouncements against him and the rebuilding of the house of God, behold, they are written in the treatise of the Book of the Kings. Then his son Amaziah became king in his place.
