And he brought up Hadassah, that is, Esther, his uncle's daughter: for she had neither father nor mother, and the maid was fair and beautiful; whom Mordecai, when her father and mother were dead, took for his own daughter. He brought up Hadassah - הדשה hadassah signifies a myrtle in Chaldee: this was probably her first or Babylonish name. When she came to the Persian court, she was called Esther, aster, or sitara, which signifies a star in Persian: the name is undoubtedly Persian. Esther was the daughter of Abihail, the uncle of Mordecai, and therefore must have been Mordecai's cousin, though the Vulgate and Josephus make her Mordecai's niece: but it is safest here to follow the Hebrew.
