On his mother's side, Mordecai was, in very deed, a member of the tribe of Judah. In any event, he was a son of Judah in the true sense of the word; he publicly acknowledged himself a Jew, and he refused to touch of the forbidden food which Ahasuerus set before his guest at his banquet.
His other appellatives likewise point to his piety and his excellencies. His name Mordecai, for instance, consists of Mor, meaning "myrrh," and Decai, "pure," for he was as refined and noble as pure myrrh. Again, he is called Ben Jair, because he "illumined the eyes of Israel"; and Ben Kish, because when he knocked at the gates of the Divine mercy, they were opened unto him, which is likewise the origin of his name Ben Shimei, for he was heard by God when he offered up prayer. Still another of Mordecai's epithets was Bilshan, "master of languages." Being a member of the great Sanhedrin he understood all the seventy languages spoken in the world. More than that, he knew the language of the deaf mutes. It once happened that no new grain could be obtained at Passover time. A deaf mute came and pointed with one hand to the roof and with the other to the cottage. Mordecai understood that these signs meant a locality by the name of Gagot-Zerifim, Cottage-Roofs, and, lo, new grain was found there for the 'Omer offering. On another occasion a deaf mute pointed with one hand to his eye and with the other to the staple of the bolt on the door. Mordecai understood that he meant a place called En-Soker, "dry well," for eye and spring are the same word, En, in Aramaic, and Sikra also has a double meaning, staple and exhaustion.
