'Shield' in the Bible

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.

I will shield this city and rescue it for the sake of my reputation and because of my promise to David my servant.'"

I will add fifteen years to your life and rescue you and this city from the king of Assyria. I will shield this city for the sake of my reputation and because of my promise to David my servant."'"
