And I will deliver thee and this city out of the hand of the
king of Assyria
So that it seems that Hezekiah's sickness was while the king of Assyria was near the city of Jerusalem, and about to besiege it, and before the destruction of the Assyrian army; unless this is said to secure Hezekiah and the inhabitants of Jerusalem from all fears of a return of that king, to give them fresh trouble: and I will defend this city;
from the present siege laid to it, ruin threatened it, or from any attack upon it, by the Assyrian monarch.
