Midrasch zu Esther 9:28

“May You pursue them in wrath and destroy them from under the heavens of the Lord” (Lamentations 3:66).
“May You pursue them in wrath and destroy them” – Jeremiah said: “May you pursue them in wrath and destroy them.” Moses said: “For I will erase [maḥo emḥe] the memory of Amalek from under the heavens” (Exodus 17:14). Shmuel said: “Amalek” – in its plain sense; “memory” – this is Haman; maḥo – in this world; emḥe – in the World to Come; “from under the heavens” – for him and for all the members of that generation [and] until the end of all generations. Rabbi Yehoshua said: So that there will not be a son and a grandson for Amalek under the heavens, so [people] will not say: This tree is Amalek’s, this camel is Amalek’s, this sheep is Amalek’s. Rabbi Eliezer said: Because it sought to eliminate Israel from under the wings of the heavens, Moses said before the Holy One blessed be He: This wicked one seeks to eliminate Israel from under Your wings. The Torah scroll that You gave them, who will read it?
Another matter: Because it sought to eliminate Israel, who are destined to be scattered from one end of the world to the other, as it is stated: “From the end of the earth to the end of the earth” (Deuteronomy 28:64).
Rabbi Eliezer says: When will the name of these be eliminated from the world, and idolatry and its worshippers will be eliminated from the world, and the Holy One blessed be He will be one in the world,⁸⁵He will be acknowledged as the one, true God. like the matter that is stated: “The Lord will be King over all the land; on that day the Lord will be one and His name one” (Zechariah 14:9)? At the time when, “may you pursue them in wrath and destroy them from under the heavens of the Lord.”
Rabbi Natan said: Haman came only to provide a remembrance for Israel.⁸⁶This is in explanation of the statement earlier that the word “memory” (Exodus 17:14) alludes to Haman. Through the story of Purim, Jews continue to preserve the memory of Amalek and its actions, as well as the requirement to destroy Amalek, as required by the Torah (Deuteronomy 25:17–19). That is what is written: “These days of Purim will not pass from among the Jews, and their memory will not cease from their descendants” (Esther 9:28).

Wisdoms have built her house (Proverbs 9:1): This is the Torah that has created all of the worlds; it hewed out pillars seven which is hewed from the seven firmaments and given to people. Another [understanding] - Wisdoms have built her house: The Holy One, blessed be He said, "If a man merits and studies Torah and wisdom, he is considered in front of Me as if he stood up entirely all of the world; it hewed out pillars seven these are seven lands - if a man merits and sustains it, he inherits seven lands, and if not, he is divided among seven lands. She prepared her meat, she mingled her wine (Proverbs 9:2): Rabbi Abahu said, "This is Esther the Queen, as at the time that trouble came to Israel in the days of Mordekhai, what did she do? She set up a meal for Achashverosh and Haman the evildoer and she got him very drunk with wine, and the evildoer thought to himself that she was granting him honor and he did not know that she opened a trap for him - from that which she got him drunk with wine, she acquired her people forever; she even prepared her table that she set herself up a table in this world and in the world to come. And what is that? That is the good name that she acquired in this world and in the world to come; since all of the holidays are to be nullified in the future but the days of Purim will not be nullified, as it is stated (Esther 9:28), 'And these days of Purim will not be rescinded from the Jews.'" Rabbi Elazar said, "Also Yom Kippur will forever not be nullified, as it is stated, 'And it will be to you for an everlasting statute to atone for the Children of Israel from all of their sins once a year.'" Another [understanding]: she even prepared her table: This is the Torah, that sets up a table for one who is involved with it, in this world and in the next world, as it is stated (Ezekiel 41:22), "and He spoke to me, 'This is the table that is in front of the Lord.'" Another [understanding]: she even prepared her table: It once happened that Rabbi Akiva was imprisoned in jail and Rabbi Yehoshua the Garsi, his student, was serving him. [On] the eve of the holiday, [the latter] departed from him and went to his house. Eliyahu came and stood at the entrance of his house. He said to him, "Peace be unto you, my teacher." He said [back] to him, "Peace be unto you, my teacher and master." He said to him, "Is there nothing that you require? He said to him, "I am a priest and I have come to tell you that Rabbi Akiva has died in jail." Immediately they both went to the jail and found the opening of the gate of the jail open and the minister of the jail was sleeping and all of the people that were in the jail were [also] sleeping; and they lay Rabbi Akiva on the bed and went out [with him]. Immediately Eliyahu, may he be remembered for the good, attended to him and took him on his shoulders. And when Rabbi Yehoshua the Garsi saw this, he said to Eliyahu, "My teacher, did you not say to me, I am Eliyahu [the] priest, and a priest is forbidden to become impure through [contact with a dead [body]!" He said [back] to him, "It is enough for you, Rabbi Yehoshua, my son, God forbid - as there is no impurity from the righteous, and also not from their students." And they carried him the whole night until they reached the mansion house of Caesarea. And when they reached there, they went up three steps and went down inclines and a cave opened in front of them and there they saw a chair and a bench and a candelabra. And they laid down Rabbi Akiva on the bed and left. And when they went out, the cave sealed and the lamp on the candelabra became lit. And when Eliyahu saw this, he opened and said, "Happy are the righteous and happy are those that toil in the Torah and happy are those that fear God - as covered and hidden and reserved for you is a place in the Garden of Eden in the future to come. Happy are you Rabbi Akiva, that you should find a resting place prepared for you at the time of your death. That is why it is stated, 'she even prepared her table.'" And it also once happened with Rabban Gamliel, that the elders were reclining [to eat] with him and Tabi, his servant, was standing to serve him. Rabbi Elazar ben Azariya said, "Woe is to you Canaan that you obligated your children [to servitude], whether they be righteous or whether they be evil." Rabbi Yishmael said, "We have found greater than this - Avraham was the great one of the world who served the Canaanites." Rabbi Tarfon said, "We have found greater than this - the High priest serves Israel on Yom Kippur." Rabban Gamliel said to them, "You have left over the honor of the Holy One, blessed be He, and you are dealing with the honor of flesh and blood? The Holy One, blessed be He, created His world, makes the wind blow, makes the sun shine, brings down the rain, makes the due appear, makes the plants grow and sets up a table in front of each and every [person], as it is written, (Psalms 23:5), 'Set a table in front of me.' And why [does He do] so much? In the merit of Torah. Therefore Shlomo prophesied and said, 'she even prepared her table.'" Rabbi Nechemiah said, "Come and see how great is the honor of Torah: It is not enough for them, for the sages, that He prepares a table for them, but it [even] adds wisdom to their wisdom. This is what is written (Proverbs 9:9), 'Give to a wise man, and he will become even wiser; inform a righteous one, and he will increase in teaching' - If you see a Torah scholar for whom words of Torah are beloved, give him wisdom and he will become even wiser; 'inform a righteous one, and he will increase in teaching' - that since he destroys his soul to hear words of Torah, it also adds fear [of God] to him."

R. Yeshoshua says: "a remembrance in the book": When Amalek came to harm Israel under the wings of their Father in heaven, Moses said before the Holy One Blessed be He: L rd of the universe, this wicked one is coming to destroy Your children under Your wings. The book of Torah that You gave them — who will read it? R. Elazar Hamodai says: When Amalek came to harm Israel under the wings of their Father in heaven, Moses said before the Holy One Blessed be He: L rd of the universe, Your children, who You are destined to scatter under the winds of heaven, viz. (Zechariah 2:10) "for as the four winds of heaven have I scattered you, etc." — this wicked one is coming to destroy them under Your wings. The book of Torah that You gave them — who will read it? R. Elazar Hamodai says: When will the name of these go lost? When idolatry will be uprooted, it and its servants, and the L rd will be One in the world, and His kingdom will endure forever and ever — at that time (Ibid. 14:3) "The L rd will go out and He will war against those nations, etc." (Ibid. 9) "And the L rd will be King over all the land, etc." (Eichah 3:66) "You will pursue them with wrath and You will destroy them." R. Yehoshua says: Haman came only as a remembrance for the generations, as it is written (Esther 9:28) "And these days of Purim will not pass from the midst (i.e., from the remembrance) of the Jews."
