'Wall' in the Bible

And I will make thee unto this people a strong 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 consume the palaces of Ben-Hadad.

And I will punish Bel in Babylon, and I will bring forth out of his mouth what he hath swallowed up; and the nations shall not flow together any more unto him: yea, the wall of Babylon is fallen.
