'Daughter' in the Bible

He was the guardian of Hadassah, that is Esther, his uncle’s daughter, for she had no father or mother. The young woman was beautiful of form and face; and when her father and mother died, Mordecai took her in as his own daughter.

Now as for Esther, the daughter of Abihail the uncle of Mordecai who had taken her in as his [own] daughter, when her turn came to go in to the king, she requested nothing except what Hegai the king’s eunuch [and attendant] who was in charge of the women, advised. And Esther found favor in the sight of all who saw her.

Then Queen Esther, the daughter of Abihail, with Mordecai the Jew, wrote with full power and authority to confirm this second letter about Purim.
