2 Chronicles 33:23-27

And humbled not himself before the LORD, as Manasseh his father had humbled himself; but Amon trespassed more and more.

And his servants conspired against him, and slew him in his own house.

But the people of the land slew all them that had conspired against king Amon; and the people of the land made Josiah his son king in his stead.
