John Gill Bible Commentary

Beware lest Hezekiah persuade you,.... To trust in the Lord, stand up in your own defence and not listen to these proposals; or, lest he "deceive you" (m); with vain words; whom he would represent not only as not being their lawful king, and therefore never gives him that title, but also as a deceiver and impostor, of whom they should be cautious, and guard against: saying, the Lord will deliver us; and therefore need not fear the boasts and threats, the force and fury, of the enemy: hath any of the gods of the nations delivered his land; over whom he presided, and to whom the people of it were devotees: out of the hand of the king of Assyria? this reasoning would have had some weight in it had the Lord God of Israel been like the gods of the nations, but he is not; he is the Former and Maker of all things, and sits in the heavens, and does whatsoever he pleases in heaven and in earth; and therefore, though they could not deliver their nations that worshipped them, it did not follow that the God of Israel could not deliver Hezekiah and his people. (m) "ne forte decipiat vos", Calvin, Vatablus; "ne seducat vos", Junius & Tremellius, Piscator.
