Ahaz slept with his fathers, and they buried him in the city, even in Jerusalem; for they didn't bring him into the tombs of the kings of Israel: and Hezekiah his son reigned in his place.
There was no Passover like that kept in Israel from the days of Samuel the prophet; neither did any of the kings of Israel keep such a Passover as Josiah kept, and the priests, and the Levites, and all Judah and Israel who were present, and the inhabitants of Jerusalem.
