2 Kings 21:23-27

Then Amon’s own officials conspired against him and assassinated him in his palace.

But the people of the land killed all those who had conspired against King Amon, and they made his son Josiah the next king.

The rest of the events in Amon’s reign and what he did are recorded in The Book of the History of the Kings of Judah.

He was buried in his tomb in the garden of Uzza. Then his son Josiah became the next king.
