Esther 2:7-8

2:7 Now he was acting as the guardian of Hadassah (that is, Esther), the daughter of his uncle, for neither her father nor her mother was alive. This young woman was very attractive and had a beautiful figure. When her father and mother died, Mordecai had raised her as if she were his own daughter.

2:8 It so happened that when the king’s edict and his law became known many young women were taken to Susa the citadel to be placed under the authority of Hegai. Esther also was taken to the royal palace to be under the authority of Hegai, who was overseeing the women.
