Esther 2:7

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.

Esther 2:20

2:20 Esther was still not divulging her lineage or her people, just as Mordecai had instructed her. Esther continued to do whatever Mordecai said, just as she had done when he was raising her.
