Nehemiah, while still in Persia, became gravely concerned for the situation in Jerusalem. He sought permission from his employer, the king of Persia, to return to his own land and direct the people in rebuilding a wall of protection around Jerusalem. When permission was granted, Nehemiah returned. Upon arrival, he set out to inspect the existing wall - largely destroyed in the Babylonian invasion - and make plans to rebuild.
Nehemiah exhorts the people to rebuild, facing persistent opposition from within and without, and with the help of God, rebuilds the city wall in an incredible 52 days. Nearly 100 years from the start of the resettlement, the wall was finally in place.
