Esther 2:2-4

2Then said the king's servants that attended upon him, Let there be maidens, virgins of beautiful countenance, sought for the king;

3and let the king appoint officers in all the provinces of his kingdom, that they may gather together all the young virgins of beautiful countenance to Shushan the fortress, to the house of the women, unto the custody of Hegai the king's chamberlain, keeper of the women; and let their things for purification be given.

4And let the maiden that pleaseth the king be queen instead of Vashti. And the thing pleased the king; and he did so.
