Esther 2:5-7King James Version (KJV)
5 Now in Shushan the palace there was a certain Jew, whose name was Mordecai, the son of Jair, the son of Shimei, the son of Kish, a Benjamite;
6 Who had been carried away from Jerusalem with the captivity which had been carried away with Jeconiah king of Judah, whom Nebuchadnezzar the king of Babylon had carried away.
7 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.
Esther 2:21-23King James Version (KJV)
21 In those days, while Mordecai sat in the king's gate, two of the king's chamberlains, Bigthan and Teresh, of those which kept the door, were wroth, and sought to lay hands on the king Ahasuerus.
22 And the thing was known to Mordecai, who told it unto Esther the queen; and Esther certified the king thereof in Mordecai's name.
23 And when inquisition was made of the matter, it was found out; therefore they were both hanged on a tree: and it was written in the book of the chronicles before the king.
