7And Mordecai had brought up Hadassah (that is, Esther), the daughter of his uncle, because she did not have a father or mother. The young woman was lovely in form and appearance, and when her father and mother had died, Mordecai had taken her in as his own daughter.
8When the king’s command and edict had been proclaimed, many young women gathered at the citadel of Susa under the care of Hegai. Esther was also taken to the palace and placed under the care of Hegai, the custodian of the women.
— Esther 2:7-8
