'Shutting' in the Bible

Now in the spring, at the time when kings go out to war, David sent Joab and his servants and all Israel with him; and they made waste the land of the children of Ammon, and took up their position before Rabbah, shutting it in. But David was still at Jerusalem.

By your help I have made a way through the wall which was shutting me in: by the help of my God I have gone over a wall.
