'Wall' in the Bible

At that time came to them Tatnai, governor on this side the river, and Shethar-boznai, and their companions, and said thus to them: Who gave you orders to build this house and to complete this wall?

Then asked we those elders: thus we said to them, Who gave you orders to build this house and to complete this wall?

For we are bondmen; yet our God hath not forsaken us in our bondage, but hath extended mercy unto us before the kings of Persia, to give us a reviving, to set up the house of our God and to repair the ruins thereof, and to give us a wall in Judah and in Jerusalem.
