The book of Ezra begins where 2 Chronicles ends. As prophesied by Isaiah (Isa. 44:28), the Persian King Cyrus had sent exiles led by Zerubbabel back to Jerusalem in 538 b.c. (Persia had defeated Babylon in 539.) Despite opposition from the non-Jewish inhabitants of Judea, and after encouragement by the prophets Haggai and Zechariah, the temple was rebuilt (515). Then in 458, Ezra led the second of three waves of returning exiles. By the time Ezra arrived, the people had again fallen into sin. Ezra preached God's word and the people repented (10:9-17). Ezra succeeded because God's hand was upon him (7:6, 9, 28; 8:18, 22, 31). This book, perhaps written by Ezra, shows God's power in covenant faithfulness, moving even pagan kings to accomplish his redemptive purposes.
