'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.

And in the drawing nigh of the turn of Esther -- daughter of Abihail, uncle of Mordecai, whom he had taken to him for a daughter -- to come in unto the king, she hath not sought a thing except that which Hegai eunuch of the king, keeper of the women, saith, and Esther is receiving grace in the eyes of all seeing her.
