2 Re 21:23

And the servants of Amon conspired against him, and slew the king in his own house. The servants of Amon conspired - What their reason was for slaying their king we cannot tell. It does not seem to have been a popular act, for the people of the land rose up and slew the regicides. We hear enough of this man when we hear that he was as bad as his father was in the beginning of his reign, but did not copy his father's repentance.
