12 because they hearkened not to the voice of Jehovah their God, but transgressed his covenant, all that Moses the servant of Jehovah commanded; and they would not hear nor do it.

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.
