...משה מן התורה מנין (בראשית ו, ג) בשגם הוא בשר המן מן התורה מנין (בראשית ג, יא) המן העץ אסתר מן התורה מנין (דברים לא, יח) ואנכי הסתר אסתיר מרדכי מן התורה מנין דכתיב (שמות ל, כג) מר דרור ומתרגמינן מירא דכיא:
... They also asked Rav Mattana: From where in the Torah is the existence of Moses [Moshe] alluded to before his birth? He replied that the verse states: “For that he also [beshaggam] is flesh; therefore shall his days be one hundred and twenty years” (Genesis 6:3). The numerical value of beshaggam is the same as that of the Hebrew name Moshe, and it is known that Moses lived a total of 120 years (see Deuteronomy 34:7). They also asked Rav Mattana: From where in the Torah can one find an allusion to the hanging of Haman? He replied: The verse states after Adam ate from the tree of knowledge: “Have you eaten of [hamin] the tree, about which I commanded you that you should not eat?” (Genesis 3:11). Hamin is spelled in the same manner as Haman: Heh, mem, nun. They also asked Rav Mattana: From where in the Torah can one find an allusion to the events involving Esther? He replied to them that the verse states: “Then My anger shall be kindled against them on that day, and I will forsake them, and I will hide My face from them, and they shall be devoured, and many evils and troubles shall come upon them; so that they will say in that day: Have not these evils come upon us because our God is not among us? And I will hide [haster astir] My face on that day for all the evil which they shall have wrought, in that they are turned to other gods” (Deuteronomy 31:17–18). They also asked him: From where in the Torah can one find an allusion to the greatness bestowed upon Mordecai? He replied: As it is written with regard to the anointing oil in the Tabernacle: “And you shall also take the chief spices, of flowing myrrh [mor deror]” (Exodus 30:23); and we translate mor deror into Aramaic as: Mira dakhya, which resembles the name Mordecai.
