12 This happened because they had not obeyed the Lord their God, but had violated his covenant-all that Moses the servant of the Lord commanded. They neither listened to the commands nor carried them out.

Matthew Henry's Commentary on 2 Kings 18:12

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.
