Esther 2:5-7

5Now there was in the citadel of Susa a Jew of the tribe of Benjamin, named Mordecai son of Jair, the son of Shimei, the son of Kish, 6who had been carried into exile from Jerusalem by Nebuchadnezzar king of Babylon, among those taken captive with Jehoiachin Hebrew Jeconiah, a variant of Jehoiachin king of Judah.

7Mordecai had a cousin named Hadassah, whom he had brought up because she had neither father nor mother. This young woman, who was also known as Esther, had a lovely figure and was beautiful. Mordecai had taken her as his own daughter when her father and mother died.
