"Whose name was Mordecai" (Esth. 2:5), because his prayer || ascended before the Holy One, blessed be He, like the scent of pure myrrh (טר לכי). "The son of Jair" (ibid.), because he enlightened (Mair) the faces (of the scholars) in Halakhah. "The son of Shimei" (ibid.), who went forth to curse David. "The son of Kish" (ibid.), of the seed of those who could use both the right hand and the left, as it is said, "The children of Ephraim, being armed and carrying bows" (Ps. 78:9).
Rabbi Simeon said: Come and see the wisdom of Mordecai, for he knew seventy languages, as it is said, "Which came with Zerubbabel, Jeshua… Mordecai, Bilshan" (Ezra 2:2), and he sat in the gates of the king to see that Esther and her maidens should not become defiled by any kind of unclean food. He heard the two eunuchs of the king speaking in the language of the Chaldees, saying: Now will the king take the afternoon sleep, and when he arises he will say, Give me a little water; let a deadly poison be given to him in the golden vessel, and he will drink thereof and die. Mordecai went in and told Esther. Now Esther told the king in the name of Mordecai, as it is said, "And Esther told the king in Mordecai's name" (Esth. 2:22). Hence (the Wise Men) have said: Whosoever tells a matter in the name of its author brings redemption into the world.
