About the Book of Ezra
Ezra and Nehemiah are books in the older part of the Bible. They are the last two books in the story of the Jews. Their people had lived as prisoners in Babylon city during 70 years. The books tell us how the people of Israel (Jews or Israelites) returned to Jerusalem from Babylon. Nebuchadnezzar had taken them to Babylon as prisoners. But Persia won a fight with Babylon. Then the king of Persia decided to send Nebuchadnezzar's prisoners back to their own countries. Cyrus, the king, asked the Jews to build God's temple in Jerusalem.
Ezra was a priest who knew God's book. And he knew the rules that it contained. He taught the people how to give pleasure to God. Then God would give a good life to them in their own country.
