The Book of Ezra records details about the Lord God continuing to help His people via Ezra in accordance with the good-message regarding the Christ. It includes information about Ezra's two journeys to Jerusalem from Babylon, building the sacrificial altar, the foundation, and the house of God according to God's instructions and the help of prophecy from Haggai and Zechariah. The chronological timeframe of the Book of Ezra begins after the Books of Esther and II Chronicles, plus Nehemiah 7:4. Ezra 1:1 occurred during the 1st year of the reign of Esther's son, Cyrus, in the same year that Esther's husband took full control of Babylon.
