2 Chronicles 24:25

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

He was thirty-two years old when he became king, and he reigned in Jerusalem eight years; and he departed with no one’s regret, and they buried him in the city of David, but not in the tombs of the kings.

So Ahaz slept with his fathers, and they buried him in the city, in Jerusalem, for they did not bring him into the tombs of the kings of Israel; and Hezekiah his son became king in his place.
