Prominent sub themes are present throughout the two books. These themes bear a striking resemblance to the exodus of the Israelites into the Promised Land: the returnees experience a second exodus to the Promised Land in the face of opposition, the Law of God lays the foundation for Israelite life and worship, and God's people receive a call to ethnic and ritual purity. And throughout its entirety we see the theme of gratitude for the hand of God working to accomplish his will. While Schoville holds that Ezra-Nehemiah was edited during the oppression of the Greeks, the editor's compilation would no doubt lift the spirits of those in any generation. Ezra-Nehemiah would call its audience to walk in faith in the ways of God rather than the dominant culture. The story of those first returnees from Babylonian exile would benefit not only the subjects of Greek rule, but all who would follow.
