Bible Verses About Walls of the Cities: Double

And the city was broken up, and all the men of war fled by night by the way of the gate between two walls, which is by the king's garden: (now the Chaldees were against the city round about:) and the king went the way toward the plain.

Ye made also a ditch between the two walls for the water of the old pool: but ye have not looked unto the maker thereof, neither had respect unto him that fashioned it long ago.
