2 Kings 14:5

And his servants arose and made a conspiracy and struck down Joash at the house of Millo as he was going down to Silla.

Pul, king of Assyria, came against the land, and Menahem gave Pul one thousand talents of silver so that his hand might be with him to strengthen the kingdom in his hand.

Then the people of the land struck down all those who had conspired against King Amon, and the people of the land made Josiah his son king in his place.

Amaziah was twenty-five years old when he became king, and he reigned twenty-nine years in Jerusalem. And his mother’s name was Jehoaddan of Jerusalem.

Now it happened as soon as the kingdom was strong in his grasp, that he killed his servants who had struck down the king his father.
