'Wall' in the Bible

be it known to the king that the Jews who have come up from near you to us have gone to Jerusalem. They are building the rebellious and wicked city. They are finishing the wall and repairing the foundation.

For we are slaves and in our bondage our God did not forsake us, and he has extended to us loyal love in the presence of the kings of Persia, to give to us deliverance [and] to set up the house of our God, to repair its ruins, and to give us a wall in Judea and Jerusalem.
