Esther 2:5 Meaning and Commentary

Esther 2:5

Now in Shushan the palace was a certain Jew
Not one of the tribe of Judah, for he was afterwards called a Benjaminite; but was so called, because he was of the kingdom of Judah, which consisted of both tribes. Jarchi says, all that were carried captive with the kings of Judah were called Jews among the nations, though of another tribe: whose name was Mordecai, the son of Jair, the son of Shimei, the son of
Kish, a Benjamite;
who was among those that came with Zerubbabel from Babylon to Jerusalem, and returned to Persia again, ( Ezra 2:2 ) ( Nehemiah 7:7 ) , though some think this was another Mordecai; (See Gill on Ezra 2:2), who descended not from Kish, the father of Saul, but a later and more obscure person.

Esther 2:5 In-Context

3 And let the king appoint local governors in all the provinces of his kingdom, and let them select fair chaste young damsels to the city Susa, into the women's apartment, and let them be consigned to the king's chamberlain, the keeper of the women; and let things for purification and other attendance be given .
4 And let the woman who shall please the king be queen instead of Astin. And the thing pleased the king; and he did so.
5 Now there was a Jew in the city Susa, and his name was Mardochaeus, the of Jairus, of Semeias, of Cisaeus, of the tribe of Benjamin;
6 who had been brought a prisoner from Jerusalem, which Nabuchodonosor king of Babylon had carried into captivity.
7 And he had a foster child, daughter of Aminadab his father's brother, and her name Esther; and when her parents were dead, he brought her up for a wife for himself: and the damsel was beautiful.
