Nehemiah was a Jewish cupbearer who lived in Babylon during the reign of Artaxerxes. At the time Jerusalem was in bad shape and it was destroyed, and when Nehemiah heard about this he was very upset. One day while Nehemiah was working the king noticed how upset he was and asked why, so Nehemiah told he and also asked if he could return to Jerusalem for a little just to help them rebuild. The king understood and said yes. When Nehemiah got too Jerusalem he had an idea to rebuild the wall and the city. His plan was that people would go back to where they lived in Jerusalem and build their part of wall and city so it was being built everywhere all at once. This idea worked beautifully and in 52 days they got the whole city built.
