Midrash su Deuteronomio 28:64

“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).
End of the Third Alphabetical Acrostic

Rabbi Ḥanina bar Pappa began: “A battering ram, a sword, and a sharp arrow…” (Proverbs 25:18). “A battering ram [mefitz]” – as in, “the Lord will scatter you [vehefitzḥa] among all the peoples” (Deuteronomy 28:64); “a sword” – as in, “I will unsheathe the sword after you” (Leviticus 26:33); “and a sharp arrow” – as in, “when I send the [evil] arrows of famine” (Ezekiel 5:16). All this for whom? For “a man who bears false witness against his friend” (Proverbs 25:18) – that is Israel, who responded and said: “This is your God, Israel” (Exodus 32:4). “A loose tooth and an unsteady foot…” (Proverbs 25:19) – Israel said before the Holy One blessed be He: Master of the universe, when You came to shepherd us, our tooth consumed and crushed others. Why then is the grazing tooth consuming us and the foot is trampling us? It is due to the confidence [we placed] in idolatry, because we betrayed our Rock.⁴⁰This is based on the continuation of the verse cited above: “Is trust in a traitor on a day of trouble” (Proverbs 25:19). “As one who removes a garment on a cold [kara] day” (Proverbs 25:20) – “and it was that when He called [kara] and they did not listen” (Zechariah 7:13).
Another matter: “[Confidence in an unfaithful man in a time of trouble is like] a loose tooth and an unsteady foot” (Proverbs 25:19) – a tooth that undermines and a foot that gives way. The Holy One blessed be He said: I said to Israel: ‘Betray idol worship and put your trust in Me,’ but they did not do so; rather, they betrayed Me and put their trust in idol worship. That is what is written: “They say to wood: You are my father” (Jeremiah 2:27). When they sinned they were exiled. When they were exiled, Jeremiah began lamenting over them, eikha.
