Esther, a cousin of Mordecai, was a member of the Jewish community in the Exilic Period who claimed as an ancestor Kish, a Benjamite who had been taken from Jerusalem into captivity. She was the orphaned daughter of Mordecai's uncle, another Benjamite named Abihail. Upon the king's orders, Esther is taken to the palace where Hegai prepares her to meet the king. Even as she advances to the highest position of the harem, perfumed with gold and myrrh and allocated certain foods and servants, she is under strict instructions from Mordecai, who meets with her each day, to conceal her Jewish origins. The king falls in love with her and makes her his Queen.
