About the Book of Nehemiah

The Book of Nehemiah is part of the Old Testament. Nebuchadnezzar, the king of Babylon had destroyed the temple in Jerusalem. Later, Artaxerxes became king of Babylon.
The Jews are God's people. They had to live in Babylon. Nebuchadnezzar had sent the Jews to live there. Later the Jews returned to Jerusalem.
This is a careful report of what happened.
They found that soldiers had destroyed the city wall. This was very important. In Deuteronomy 7:3-4, God tells the Jews that they must not marry people who were not Jews. This is because people from other countries worshipped other gods.
Nehemiah reports what the Jews' enemies did. The Jews were building the city wall again. Then Jerusalem would become a powerful city. So their enemies tried to stop them.
The Jews knew that God would keep them safe. He did this while they built the city wall again.
