[2] The Book of Ezra is divided into two parts: the first telling the story of the first return of exiles in the first year of Cyrus the Great (538 BC) and the completion and dedication of the new Temple in Jerusalem in the sixth year of Darius I (515 BC); the second telling of the subsequent mission of Ezra to Jerusalem and his struggle to purify the Jews from marriage with non-Jews.
In the book's recurring narrative pattern, the God of Israel three times inspires a king of Persia to commission a leader from among the Jews to carry out a mission: the first to rebuild the Temple, the second to purify the Jewish community, and the third to seal the holy city behind a wall.
The book contains several documents presented as historical inclusions, written in Aramaic while the surrounding text is in Hebrew (1:2–4, 4:8–16, 4:17–22, 5:7–17, 6:3–5, 6:6–12, 7:12–26) [4] In the early 6th century BC, the Kingdom of Judah rebelled against the Neo-Babylonian Empire and was destroyed.
The same period saw the rapid rise of Persia, previously an unimportant kingdom in present-day southern Iran, to a position of great power, and in 539 BC Cyrus II, the Persian ruler, conquered Babylon.
[5] It is difficult to describe the parties and politics of Judea in this period because of the lack of historical sources, but there seem to have been three important groups involved: the returnees from the exile who claimed the reconstruction with the support of Cyrus II; "the adversaries of Judah and Benjamin"; and a third group, "people of the land", who seem to be local opposition against the returnees building the Temple in Jerusalem.
[11] Koresh of Ezra 1:1 is called "king of Persia", which title was introduced by Cyrus the Great some time after he defeated Astyages of Media (585–550 BC).
[13] The contents of Ezra–Nehemiah are structured in a theological rather than chronological order: "The Temple must come first, then the purifying of the community, then the building of the outer walls of the city, and so finally all could reach a grand climax in the reading of the law.
[17] This concern with a schematic pattern-making, rather than with history in the modern sense of a factual account of events in the order in which they occurred, explains the origin of the many problems which surround both Ezra and Nehemiah as historical sources.
[19] More recently it has been increasingly recognised that Ezra, Nehemiah and Chronicles all have extremely complex histories stretching over many stages of editing,[20] and most scholars now are cautious of assuming a unified composition with a single theology and point of view.
