The story recorded in the book of Esther took place in Susa. It happened after Cyrus allowed Jews to return to Judah and rebuild the temple. It happened before Ezra and Nehemiah were leaders in Jerusalem.
All Jews who had been forced to leave the southern kingdom were allowed to move back. But many chose to continue living in the lands ruled over by the Persian government. Xerxes ruled over the entire Persian kingdom. He held a banquet for other leaders in that kingdom. He showed them how rich he was and how much power he had. But Queen Vashti challenged his authority.
At that time in Persia, husbands had authority to give commands to their wives. Wives were required to obey their husband’s orders. Xerxes was very angry that the queen disobeyed him. He followed the suggestions of his advisers and attendants about what to do. A new queen would take Vashti’s place. Xerxes would choose the new queen from among a group of virgins. These young women were forced to leave their families to serve the king. They served him by becoming concubines. Xerxes chose Esther to be the new queen.
God’s people were supposed to marry people who worshipped only God. But Esther wasn’t given the choice whether or not to marry Xerxes. Esther’s cousin Mordecai helped her and supported her as much as he could. He warned her not to tell anyone that she was a Jew. He also warned her about plans to kill Xerxes. Esther used her authority as queen to help save Xerxes from being killed. The two officers who made the plans against Xerxes were put to death.
