Esther 2:14-15

14In the evening she would go in, and in the morning she would return to the second harem in custody of Shaashgaz, the king's eunuch, who was in charge of the concubines. She would not go in to the king again, unless the king delighted in her and she was summoned by name.

15When the turn came for Esther the daughter of Abihail the uncle of Mordecai, who had taken her as his own daughter, to go in to the king, she asked for nothing except what Hegai the king's eunuch, who had charge of the women, advised. Now Esther was winning favor in the eyes of all who saw her.
