9 Now in the fourth year of King Hezekiah, which was the seventh year of Hoshea, son of Elah, king of Israel, Shalmaneser, king of Assyria, came up against Samaria, shutting it in with his armies. 10 And at the end of three years they took it; in the sixth year of Hezekiah's rule, which was the ninth year of Hoshea, king of Israel, Samaria was taken. 11 And the king of Assyria took Israel away as prisoners into Assyria, placing them in Halah and in Habor on the river Gozan, and in the towns of the Medes; 12 Because they did not give ear to the voice of the Lord their God, but went against his agreement, even against everything ordered by Moses, the servant of the Lord, and they did not give ear to it or do it.

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.
