Midrash su Esdra 4:21

“It was during the days of Aḥashverosh; that [hu] Aḥashverosh; that [hu] Aḥashverosh who reigned from India to Kush, one hundred and twenty-seven provinces” (Esther 1:1).¹What follows is a series of wordplays on the name Aḥashverosh.
Rabbi Yehoshua ben Korḥa said: Who blackened [hishḥir] the faces of Israel like the bottom of a pot. Rabbi Berekhya said: Who weakened [hikḥish] the head of Israel with fasting and abstinence. Rabbi Levi said: Who gave them gall and wormwood to drink [hishka]. Rabbi Yuda son of Rabbi Simon said: Who sought to undermine the foundation of Israel.²Literally, to undermine the egg of Israel. The wordplay with the name Aḥashverosh is obscure in this case. Perhaps it involves the word הוריש, meaning to dispossess or destroy. Rabbi Taḥlifa bar bar Ḥana said: Who was the brother [aḥ] of a leader [rosh], the brother of Nebuchadnezzar. Was he his brother? Was not this one a Chaldean and that one a Median? Rather, this one canceled the construction of the Temple, and that one destroyed it; therefore, Scripture equated them. That is what is written: “Even one who is lax in his work is brother to a master of destruction.” (Proverbs 18:9). “Even one who is lax in his work,” that is Aḥashverosh, who canceled the construction of the Temple. “Is brother to a master of destruction,” that is Nebuchadnezzar, who destroyed the Temple.
Alternatively, “Aḥashverosh” – Rabbi Yehuda and Rabbi Neḥemya: One said: “Aḥashverosh,” who killed his wife [Vashti] because of his beloved one [Haman]; “that Aḥashverosh,” who killed his beloved one [Haman] because of his wife [Esther]. Rabbi Neḥemya said: “Aḥashverosh,” who canceled the construction of the Temple; “that Aḥashverosh,” who decreed that it should be rebuilt. Was it him who decreed? Was it not Cyrus who decreed? Rather, it is written: “During the first year of King Cyrus” (Ezra 6:3). During that year, all his advisers came to him; they said to him: ‘Your father decreed about it that it shall not be rebuilt, and you decree about it that it shall be rebuilt? Does a king abrogate the decrees of another king?’ He said to them: ‘Bring me the copies of the decrees.’ Immediately, they brought them to him. That is what is written: “A scroll was found in Aḥmeta in the capital” (Ezra 6:2). What was written in it? “Now, issue a decree to cancel” (Ezra 4:21). He said to them: ‘Is ‘forever’ written? It is only written: “Until a decree from me will be issued.” Who can say to me that were my father alive, he would not have built it?’ Therefore, he is included with the prophets; that is what is written: “The elders of the Jews built and prospered [in accordance with the prophecy of Haggai the prophet and Zechariah son of Ido, and built and finished, by the decree of the God of Israel, and by the decree of Cyrus, and Darius, and Artaḥshasta³The midrash identifies Artaḥshasta king of Persia as Aḥashverosh. king of Persia]” (Ezra 6:14).

“As when a man fled from the lion and a bear attacked him; he came home and leaned his hand on the wall, and a snake bit him” (Amos 5:19).
Rabbi Yuda son of Rabbi Simon began: “As when a man fled from the lion and a bear attacked him; he came home and leaned his hand on the wall, and a snake bit him.” Rabbi Huna and Rabbi Aḥa in the name of Rabbi Ḥama bar Rabbi Ḥanina said: “As when a man fled from the lion,” that is Babylonia, according to: “The first was like a lion” (Daniel 7:4); “and a bear attacked him,” that is Media, according to: “And behold, another beast, a second one, resembling a bear” (Daniel 7:5).
Rabbi Yoḥanan said: le dev is written [“a second one, resembling a bear (dov)].”⁹ The words in the verse in Daniel 7:5 domeh le-dov, “resembling a bear,” could be vocalized domeh le-dev, meaning resembling a wolf, as dev can mean wolf in Aramaic. This is the opinion of Rabbi Yoḥanan, as Rabbi Yoḥanan said: “Therefore, a lion from the forest smote them” (Jeremiah 5:6), that is Babylonia; “a wolf of the deserts will plunder them” (Jeremiah 5:6), that is Media; “a leopard lies in wait near their cities” (Jeremiah 5:6), that is Greece; “everyone who emerges from them will be mauled” (Jeremiah 5:6), that is Edom; “he comes home” (Amos 5:19), that is Greece when the Temple stood; “and a snake bit him” (Amos 5:19), that is Edom, as it is stated: “Its sound will go forth like a snake” (Jeremiah 46:22).
Likewise, it says: “Open for me, my sister, my love, my dove, my faultless one,” (Song of Songs 5:2). “Open for me, my sister,” that is Babylonia; “my love,” that is Media; “my faultless one,” in Greece; “my dove,” in Edom, as throughout the days of Greece[’s hegemony] the Temple was standing and Israel was offering doves and pigeons on the altar.
Rabbi Pinḥas and Rabbi Levi in the name of Rabbi Ḥama bar Ḥanina offered an interpretation [of “In my distress I called to the Lord and to my God I cried; from His Sanctuary He heard my voice, and my cry before Him came into His ears” (Psalms 18:7)]: It is written: “In my distress I called to the Lord,” in Babylonia; “and to my God I cried,” in Media; from His Sanctuary He heard my voice,” in Greece, as Rabbi Huna himself said: “My dove,” in Greece, as throughout the days of Greece, the Temple was standing and Israel was offering there doves and pigeons on the altar. That is: “from His Sanctuary He heard my voice and my cry before Him came into His ears,” in the kingdom of Edom.
Another matter: “ As when a man fled from the lion,” that is Nebuchadnezzar; “and a bear attacked him,” that is Belshatzar; “he came home and leaned his hand on the wall, and a snake bit him,” that is Haman, who would crush the people like a snake. That is as it is written: “Reḥum the commander and Shimshai the scribe” (Ezra 4:8), that is the son of Haman; “wrote a letter…to Artaxerxes the king, as follows” (ibid.). And what was written in it? “Now issue a decree to cease, and that this city not be rebuilt ….” (Ezra 4:21), [“they will no longer pay] minda” (Ezra 4:13), that is land tax; “belo” (ibid.), that is the poll tax; and “halakh” (ibid.), that is the king’s service; “and the revenue of the kings will be harmed” (ibid.). Rav Huna and Rabbi Pinḥas said: Even things with which the kingdom entertains itself, e.g., theaters and circuses, this people harms. When he sent it, it was received by the king, and he canceled work on the Temple. When they saw that, everyone began screaming: 'Woe [vai];' “it was [vayhi] during the days of Aḥashverosh” (Esther 1:1).
