Esther 2:20

Esther still had not revealed her lineage or her people, just as Mordecai had instructed. She obeyed Mordecai’s command, as she had done under his care.

Esther had not yet shewed her kindred nor her people; as Mordecai had charged her: for Esther did the commandment of Mordecai, like as when she was brought up with him.
