Matthew Poole and continuators on 2 Chronicles 24:25

25 And when they were departed from him, (for they lest him in great diseases) his own servants conspired against him, for the blood of the sons of Jehojada 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.

[illegible: 1 word]. 26. 42. and in Cicero and other profane Authors. Or he might kill other sons of Jehojadah with him, either because they owned him in what he had said; or lest they should revenge his death.
