A Jew named Nehemiah lived in Persia and worked for King Artaxerxes. Nehemiah received a report that the walls around Jerusalem were broken down, so he returned to Jerusalem to help rebuild the city walls. The walls around the city helped protect the city against armies and invaders.
The Book of Nehemiah is named for a Jewish leader named Nehemiah. Translators can use the traditional title "Nehemiah." Or they may choose a clearer title, such as "The Book about Nehemiah."
Foreigners worshiped many false gods. Yahweh did not allow his people to marry foreigners because he knew this would cause the people of Israel to worship false gods.
Many of the Jews remained in Babylon instead of returning to the Promised Land. Many of them were successful in Babylon and desired to remain there. However, this meant that they were unable to worship Yahweh in Jerusalem as their ancestors had done.
The Book of Nehemiah uses the term "Israel" to refer to the kingdom of Judah. It was mostly made up of the tribes of Judah and Benjamin. The other ten tribes had ended their loyalty to any kings descended from David. God allowed the Assyrians to conquer the other ten tribes and take them into exile. As a result, they mixed with other people groups and did not return to the land of Israel.
Some of the events in the Book of Nehemiah are not told in the order they actually happened. Translators should pay attention to notes that signal when events are probably out of order.
