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 shields, nor cast a bank against it. By the way that he came, by the same shall he return, and shall not come into this city, saith the LORD. For I will defend this city to save it for mine own sake, and for my servant David’s sake.
The LORD assured Hezekiah that the king of Assyria would not enter Jerusalem or get near enough to attack it. God would defend the city and send back the invader the way that they came.
