9 In the fourth year of Hezekiah and the seventh year of Hoshea son of Elah king of Israel, Shalmaneser king of Assyria attacked Samaria. He threw a siege around it 10 and after three years captured it. It was in the sixth year of Hezekiah and the ninth year of Hoshea that Samaria fell to Assyria. 11 The king of Assyria took Israel into exile and relocated them in Halah, in Gozan on the Habor River, and in towns of the Medes. 12 All this happened because they wouldn't listen to the voice of their God and treated his covenant with careless contempt. They refused either to listen or do a word of what Moses, the servant of God, commanded.

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.
