Midras Ester 3:15: Ein Yaakov (Glick Edition), Mekhilta DeRabbi Yishmael, Esther Rabbah & Midrash Tehillim

R. Abba b. Cahana based his [Purim] lecture on this passage (Ecc. 2, 26) For to a man who is good in His presence He giveth wisdom and knowledge and joy, this refers to Mordecai, the upright; but to the sinner he giveth employment to gather up and to bring together, that refers to Haman; that he may give it to him that is good before God, refers to Mordecai, concerning whom it is written (Est. 8, 2) And Esther appointed Mordecai over the house of Haman. Rabba b. Uphran based his [Purim] lecture on the following passage (Jer. 49, 39) And I will set up my thrown in Elam, and I will destroy thence kings and princes; i.e., kings, refers to Vashti, and princes, refers to Haman and his ten sons. R. Dimi b. Isaac based his [Purim] lecture on (Fol. 11) this passage (Ezra, 9, 9) For. we. are bondmen; yet in our bondage hath our God not forsaken us, but hath extended unto us kindness before the kings of Persia. When did He extend unto us kindness? In the time of Mordecai. R. Chanina b. Papa based his [Purim] lecture on this passage (Ps. 66, 12) Thou hast caused men to ride over our heads; we went through fire and through water; but Thou didst bring us out unto abundance, i.e., through fire, refers to the time of Nebuchadnezzar, the wicked; through water, refers to the time of Pharaoh. But Thou didst bring us out unto abundance, refers to the time of Haman. R. Jochanan based his lecture on this passage (Ib. 98, 3) He hath remembered His mercy and His faithfulness to the house of Israel; all the ends of the earth have been the salvation of our God. When did all the ends of the earth see it? In the time of Mordecai and Esther. Resh Lakish based his lecture on this passage (Prov. 28, 15) As a roaring lion and greedy bear, so is a wicked ruler over a poor people. As a roaring lion, refers to Nebuchadnezzar concerning whom it is written (Jer. 4, 7) The lion is come up from his lair. Greedy bear, refers to Ahasuerus, about whom it is written (Dan. 7, 5) And behold, there was another, a second beast, like a bear. Concerning which R. Joseph was taught that this refers to the Persians who eat and drink like a bear, and are fleshy like a bear, and let their hair grow like a bear, and have no repose like a bear; wicked ruler, refers to Haman; over a poor people, refers to Israel, who were then poor in meritorious deeds. R. Nachman b. Isaac based his lecture on this passage (Ps. 124, 2) If it had not been the Lord who was for us, when men rose up against us. Men, — not a king (referring to Haman). Raba based his lecture on this passage (Prov. 29, 2) When the righteous are in authority, the people will rejoice; but when the wicked rule, the people groan; i.e., when the righteous rule, refers to Mordecai and Esther, [then] the people rejoice, as it is written (Est. 8, 15) And Mordecai went out from the presence of the king, etc. And the city of Shushan was glad and joyful. But when the wicked rule, this refers to Haman, [then] the people groan, and so says the passage (Ib. 3, 15) And the king and Haman sat down to drink, but the city of Shushan was perplexed. R. Mathna preached with the following passage (Deut. 4, 7) For what great nation is there that hath God so nigh unto it? R. Ashi recited with the following passage (Ib. ib. 34) Or hath God essayed to go to take himself a nation from the midst of a nation.

(Exodus 14:3) "And Pharaoh will say about the children of Israel: They are nevuchim in the land": "nevuchim" is "confounded," as in (Joel 1:18) "How the beasts groan! The herds of cattle navochu!" Variantly: "nevuchim" — "bewildered," as in (Esther 3:15) "And the king and Haman sat down to feast, and the city of Shushan navochah." Variantly: "And Pharaoh said": He said and he did not know what he was saying. (i.e., unbeknownst to him he was prophesying. On the surface) he was saying that Moses was leading them without knowing where — but "nevuchim" (prophetically) intimates Moses, viz. (Devarim 32:49) "Ascend the Mount Avarim, Mount Nevo, (short for 'nevuchim')." Variantly: "And Pharaoh said," without knowing what he was saying, viz.: Israel are destined to cry ("livkoth" as in "nevochim") in the desert, viz. (Numbers 14:1) "And the entire congregation lifted their voices and the people cried (vayivku)" Israel are destined to fall in the desert, viz. (Ibid. 29) "In this desert shall your carcasses fall."

“The couriers went out urgently by the king’s command, and the order was issued in the Shushan citadel; the king and Haman sat to drink, and the city of Shushan was confounded” (Esther 3:15).
“The couriers went out urgently by the king’s command… the king and Haman sat to drink.” Rabbi Ḥanin said: Anyone who says that the All-Merciful is forbearing, his innards will be forborne. Rather, He withholds His anger, but [later] collects His due. He said to the tribes: ‘You sold your brother while eating and drinking. I will do the same to you;’²³Joseph’s brothers “sat down to eat a meal” (Genesis 37:25) when they came up with the idea of selling Joseph into slavery. that is what is written: “And the king and Haman sat to drink.”
There was a certain man of Israel who went to the marketplace to purchase a litra of meat or a bunch of greens; a Persian choked him and said to him: ‘Tomorrow I will kill you and spend your money’; that is what is written: “And the city of Shushan was confounded.”
Rabbi Yissakhar of Kefar Mandi said: See how long it takes for the resolution [of the statement] of one who forgave, saying: “It was not you who sent me here, but rather God…” (Genesis 45:8).²⁴Joseph to his brothers. The punishment for the sale of Joseph was in effect until the days of Mordekhai; for one who does not forgive, all the more so.
