“Now there was a Jew in Susa the capital, whose name was Mordecai, son of Jair, son of Shimei, son of Kish, of the tribe of Benjamin. The family of Kish had been carried away from Jerusalem, among the captives carried away with King Jeconiah of Judah, whom King Nebuchadnezzar of Babylon had captured. Mordecai had brought up Hadassah, that is Esther, his cousin. She did not have a father or mother. She was the daughter of his uncle, Aminadab. Esther was fair and beautiful in appearance. When her parents died, he brought her up to womanhood as his own daughter.”
Mordecai was a Benjaminite, the same as King Saul, and thus part of Judah. His family was brought into captivity by King Nebuchadnezzar of Babylon with the sitting king of Judah in 587 BCE. Things turned better for the captured Jews under the Persian kings, especially after King Cyrus in 539 BCE. This is about 50 years after that. Anyway, Mordecai’s uncle Aminadab and his wife had died, so that he took care of their young daughter Esther, who was his first cousin. He was either her foster father or adopted father, but really was a first cousin, since their father’s were brothers. Once again, there are slight differences between the Hebrew and Greek text. Aminadab was not mentioned in the Hebrew text, only in the Greek text. Also the Jewish name of Esther is only found in the Hebrew text as Hadassah, but not in the Greek text.
