And the Jews that were in Shushan gathered themselves together on the fourteenth day also of the month Adar, and slew three hundred men in Shushan; but on the spoil they laid not their hand.

"THERE was a certain Jew in Shushan, the capital, whose name was Mordecai" (Esth. 2:5). Rabbi Shema'iah said: Was there then no other Jew in Shushan, the capital, except Mordecai alone? Lo! it is written, "And the Jews that were in Shushan" (Esth. 9:15). But because he was a Jew, and a direct descendant of the patriarchs and also of the royal seed, and he was engaged in (the study of) the Torah all his days, and he was not defiled by any forbidden food in his mouth, therefore was his name called "a Jew."
