In which book is Cyrus' decree calling the Jews to return to Jerusalem found?

The decree by Cyrus calling the Jews to return to Jerusalem is found in the book of Ezra. This event is significant as it marks the beginning of the restoration period for the Jewish people after their Babylonian exile. In Ezra 1:1-4, it is documented that King Cyrus of Persia authorized the return and provided resources to rebuild the temple in Jerusalem. This decree was pivotal for the Jewish community as it allowed them to reclaim their homeland and restore their religious practices, which had been deeply affected during the exile.

The other books mentioned also contain important messages and prophecies related to the Jewish people but do not specifically document the decree itself as Ezra does. For instance, Jeremiah includes prophecies about the exile and future restoration, while Isaiah contains messages of hope but not the decree. The name Darius refers to a historical figure associated with furthering the rebuilding process, but he is not the one who issued the initial decree for the return. Thus, Ezra is the correct answer that directly addresses Cyrus' call for the Jews to return.
