9 During the fourth year of Hezekiah's reign, which was the seventh year of King Hoshea's reign in Israel, King Shalmaneser of Assyria attacked the city of Samaria and began a siege against it. 10 Three years later, during the sixth year of King Hezekiah's reign and the ninth year of King Hoshea's reign in Israel, Samaria fell.

Commentary on 2 Kings 18:9-16
(Read 2 Kings 18:9-16)
The descent Sennacherib made upon Judah, was a great calamity to that kingdom, by which God would try the faith of Hezekiah, and chastise the people. The secret dislike, the hypocrisy, and lukewarmness of numbers, require correction; such trials purify the faith and hope of the upright, and bring them to simple dependence on God.
