2Ch 2 Chronicles, chapter Second Book of Chronicles, chapter 24
And when they were departed from him — for they left him in great diseases — his own servants conspired against him for the blood of the sons of Jehoiada the priest, and slew him on his bed, and he died; and they buried him in the city of David, but they buried him not in the sepulchres of the kings. 2Ki 12:20; 2Ki 21:18; 2Ki 21:26
