The Book of Nehemiah is a book of the Hebrew Bible. Told largely in the form of a first-person memoir, it concerns the rebuilding of the walls of Jerusalem by Nehemiah, a Jew who is a high official at the Persian court, and the dedication of the city and its people to God's laws (torah). The events take place in the second half of the 5th century BCE, and together with the Book of Ezra, it represents the final chapter in the historical narrative of the Hebrew Bible.

The book tells how Nehemiah, at the court of the king in Susa, is informed that Jerusalem is without walls and resolves to restore them. The king appoints him as governor of Judah and he travels to Jerusalem. There he rebuilds the walls, despite the opposition of Israel's enemies, and reforms the community in conformity with the law of Moses. After an absence in Susa he returns to find that the Israelites have been backsliding, taking non-Jewish wives, and stays to enforce the Law. (Summary by Wikipedia)
