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, Ezr 2:2, though some think this was another Mordecai; See Gill on Ezr 2:2, who descended not from Kish, the father of Saul, but a later and more obscure person.
