(32-34) This may be, as Mr. Cheyne supposes, an after addition to the original prophecy. Isaiah may have spoken it a little later, in which case it was quite natural for an editor to append it here, as belonging to the same crisis. But it seems better to see here a return to the subject of the king of Assyria, after the parenthetic address to Hezekiah. The repetition of 2 Kings 19:28 in 2 Kings 19:33 favours this view.

32 Therefore thus saith the LORD concerning the king of Assyria, He shall not come into this city, nor shoot an arrow there, nor come before it with shield, nor cast a bank against it.
33 By the way that he came, by the same shall he return, and shall not come into this city, saith the LORD.
34 For I will defend this city, to save it, for mine own sake, and for my servant David's sake.
