This chapter begins our study of the reign of king Hezekiah over Judah.
This passage records the reigns of five kings of Israel and one king of Judah (in addition to the reign of Azariah of Judah in the first seven verses of the chapter). It is mostly a story of conspiracies and short reigns.
From now on out, all the kings of Israel do evil in the sight of the Lord and only some of the kings of Judah do good. Asa is especially interesting.
