Esther 2:3

2:3 And let the king appoint officers throughout all the provinces of his kingdom to gather all the attractive young women to Susa the citadel, to the harem under the authority of Hegai, the king’s eunuch who oversees the women, and let him provide whatever cosmetics they desire.

Esther 2:14-15

2:14 In the evening she went, and in the morning she returned to a separate part of the harem, to the authority of Shaashgaz the king’s eunuch who was overseeing the concubines. She would not go back to the king unless the king was pleased with her and she was requested by name.

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.
