Esther 2:18-20

18Then the king held a great banquet, Esther’s banquet, for all his officials and his servants; and he made a festival for the provinces and gave gifts in accordance with the resources of the king.

19And when the virgins were gathered together the second time, Mordecai was sitting at the king’s gate.

20Esther had not revealed her family or her people [that is, her Jewish background], just as Mordecai had instructed her; for Esther did what Mordecai told her just as when she was under his care.
