Esther 2:15

2:15 When it became the turn of Esther daughter of Abihail the uncle of Mordecai (who had raised her as if she were his own daughter) to go to the king, she did not request anything except what Hegai the king’s eunuch, who was overseer of the women, had recommended. Yet Esther met with the approval of all who saw her.
