Musar zu Bereschit 3:11

When the Talmud asked how we know from the Torah that there would be a Moses, a Haman, a Mordechai and an Esther, these are not idle questions. From the answer the Talmud gives it is evident that there must be a deeper reason for such enquiries. In the case of Moses, the Talmud cites Genesis 6,3 בשגם הוא בשר, that G–d indicated that He made an allowance for the spiritual inadequacies of man inasmuch as part of man is physical. The letters in the word בשגם have a numerical value of 345, the same as the numerical value of the name משה. The Torah alludes to an eventual Haman with the words המן העץ in Genesis 3,11. The letters of Haman are the same as the word Ha-min. When answering the question where Esther is alluded to in the Torah, the Talmud cites ואנכי הסתר אסתיר את פני, "I will keep My face hidden" (Deut 31,18). We have an allusion to Mordechai in the Torah, as we mentioned earlier, based on Exodus 30,23 ואתה קח לך בשמים ראש מר דרור, "And you, take yourself choice spices Mor deror." The translation of this spice in Aramaic is מירא דכיא.
