What Does the Book of Nehemiah Contribute to the Bible?

Nehemiah closes the Old Testament's historical narrative, tracing Israel's journey from exile back to the promised land as a purified people prepared for the Messiah.

Nehemiah completes the historical record of God’s great narrative of His work with the Jewish people in the OT—from the call of Abraham and the exodus from Egypt, through the initial conquest and the reigns of the kings, to the Babylonian exile and the return of the Jewish people to the promised land. As the book concludes, Israel is a purified people, restored to the land of promise, worshiping in a rebuilt temple—all things necessary and in preparation for the coming of Messiah.
