Midrasz do Lamentacje Jeremiasza 3:66

“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).

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."
