2 Kings 18:1

Hezekiah. From now on the kings whose records will appear are kings of Judah. When Hezekiah came to the throne—probably as coregent with his father Ahaz—Israel was almost at the close of its tragic history. Judah continued for nearly a century and a half longer. Walking in the ways of the nations round about, the people fell a prey to those nations. Ahaz, Hezekiah’s predecessor, had gone far toward bringing Judah down to the same level as Israel. The worship of heathen gods was encouraged, the Temple of the Lord was devoted to the worship of idols, and tribute was paid to Assyria. Hezekiah made a sharp and quick reversal in the religious and political policies of his father. The Temple was cleansed, the worship of false gods rooted out, submission to Assyria after a time abandoned, and the nation brought closer to righteousness and God.
