Behold thou hast heard all that the kings of the Assyrians hare done to all countries which they have destroyed, and canst thou be delivered?

Behold, thou hast heard what the kings of Assyria have done to all countries, destroying them utterly; and shalt thou be delivered?

Lo, thou hast heard that which the kings of Asshur have done to all the lands, to devote them, and thou art delivered!

No doubt the story has come to your ears of what the kings of Assyria have done to all lands, putting them to the curse: and will you be kept safe from their fate?

Behold, you have heard about all that the kings of the Assyrians have done to all the lands that they have conquered, and so, how can you be delivered?

Ecce tu audiisti quae fecerunt reges Assur universis terris, quomodo vastaverunt eas; et tu liberaberis?

Behold, thou hast heard. Here we ought to observe a twofold comparison; for he compares Hezekiah to other kings of Judah who preceded him, because he was inferior to them, and yet they were vanquished by the kings of Assyria; and Sennacherib, on the other hand, having obtained greater power than all the rest, is more daring and insolent. It followed, that Hezekiah could not resist him. The other comparison is that of the kings of Assyria, and Sennacherib himself, with the idols of the nations; for if the idols could not protect the nations that adored them, consequently neither will the God of Israel defend the nation by which he is adored. When we thus read that singular assaults of temptations were directed against the faith of Hezekiah, let us prepare ourselves for the contest by being equipped with the same armor. Even while leisure is granted to us, let us endeavour to fortify ourselves early, in order that, when we come into such a field of battle, we may fight courageously. And if Satan taunt us with the destruction of many nations, we must attend to the difference of our condition; because, although we are liable to similar calamities, still we have assured hope of our salvation, of which they are destitute.

And shalt thou be delivered? - How will it be possible for you to stand out against the conquerors of the world?

Behold, thou hast heard what the kings of Assyria have done to all lands, by destroying them utterly,.... He boasts of the achievements of himself and his ancestors, and of more than was true; and which, if it had been true, was more to their disgrace than honour, namely, utterly to destroy kingdoms, and their inhabitants, to gratify their lusts; but though many had been destroyed by them, yet not all; not Ethiopia, whose king was come out to make war with him, and of whom he seems to be afraid; nor Egypt, which was in confederacy with Ethiopia; nor Judea, he was now invading; but this he said in a taunting way, to terrify Hezekiah:
and shalt thou be delivered? canst thou expect it? surely thou canst not. Is it probable? yea, is it possible thou shouldest be delivered? it is not; as sure as other lands have been destroyed, so sure shall thine.

all lands-- (Isaiah 14:17). He does not dare to enumerate Egypt in the list.
