'Wall' in the Bible

And I will make thee unto this people a fortified brazen wall; and they shall fight against thee, but they shall not prevail against thee; for I am with thee to save thee and to deliver thee, saith Jehovah.

And I will kindle a fire in the wall of Damascus, and it shall devour the palaces of Ben-hadad.

And I will execute judgment upon Bel in Babylon, and I will bring forth out of his mouth that which he hath swallowed up; and the nations shall not flow any more unto him: yea, the wall of Babylon shall fall.
