'Uncle' in the Bible

and he is supporting Hadassah -- she is Esther -- daughter of his uncle, for she hath neither father nor mother, and the young woman is of fair form, and of good appearance, and at the death of her father and her mother hath Mordecai taken her to him for a daughter.

Now when the turn of Esther, the daughter of Abihail the uncle of Mordecai, who had taken her for his daughter, was come to go in unto the king, she required nothing but what Hegai the king's chamberlain, the keeper of the women, appointed. And Esther obtained favour in the sight of all them that looked upon her.
