The story of King Cyrus of Persia allowing the Jews to return to Jerusalem to rebuild the temple teaches that opposition can sometimes lead to positive outcomes. In this case, the Jews had been exiled from Jerusalem and were not allowed to return to their homeland. However, King Cyrus opposed the previous policy of exile and allowed the Jews to return to Jerusalem and rebuild the temple. This decision likely faced opposition from those who supported the policy of exile, but ultimately it led to a positive outcome for the Jews and allowed them to reclaim their homeland and rebuild their religious center.
