Midrash su Deuteronomio 32:35

Rabbi Levi in the name of Rabbi Shmuel bar Naḥman said: It is written: “The hair of His head like pure wool” (Daniel 7:9); that He has no debt to any creature. Rabbi Yudan in the name of Rabbi Ayevu: It is written: “I have trodden a winepress alone and from the peoples there was no man with Me...” (Isaiah 63:3). Does the Holy One blessed be He need the help of the nations, that He said: “And from the peoples there was no man with Me?” Rather, this is what the Holy One blessed be He said: When I examine the ledgers of the nations of the world and no merit will be found for them before Me, at that moment, “I trod on them in My wrath and I trampled them in My fury” (Isaiah 63:3).
Rabbi Pinḥas and Rabbi Ḥilkiyya said in the name of Rabbi Simon: It is written: “It shall be on that day that I will seek to destroy all the nations [that come against Jerusalem]” (Zechariah 12:9). Will seek? Is there anyone preventing Him? Rather, this is what the Holy One blessed be He is saying: When I examine the ledgers of the nations of the world and no merit will be found for them before Me, at that moment, I will seek to destroy all the nations.
Rabbi Simon in the name of Rabbi Yoḥanan: It is written: “Vengeance and recompense are Mine at the time that their foot will falter” (Deuteronomy 32:35). Is it heroism for a person to say that when the enemies of Israel¹²“Enemies of Israel” refers to Israel. Rabbinic custom was to substitute “enemies of Israel” for Israel when referring to Israel’s evil deeds or the consequences thereof. falter, I will punish them? Rather, this is what the Holy One blessed be He said: When they cease fulfilling the mitzvot that are customary¹³Hebrew regilot, a play on regel, foot, in the verse. among them, and no merit will be found for them before Me, at that moment, “vengeance and recompense are Mine.”
Rabbi Berekhya in the name of Rabbi Levi, and Rabbi Huna in the name of Rabbi Levi, and Rabbi Yudan in the name of Rabbi Levi, the three of them said one verse: “Your hand will find all Your enemies; Your right hand will find [timtza] Your foes” (Psalms 21:9). Your hand will be present [metzuya] to repay Your enemies, You will present [tamtze] the attribute of justice to them, You will present [tamtze] them with how few are the good deeds they performed; therefore, it says: “Your hand will find all Your enemies.”

THE DEATH OF SARAH AND THE STORY OF ISAAC AND REBECCA
SIX (people) were called by their names before they were created, and they are: Isaac, Ishmael, Moses, Solomon, Josiah, and King Messiah.

Rabbi Jehudah said: Rebecca was barren for twenty years. After twenty years (Isaac) took Rebecca and went (with her) to Mount Moriah, to the place where he had been bound, and he prayed on her behalf concerning the conception of the womb; and the Holy One, blessed be He, was entreated of him, as it is said, "And Isaac intreated the Lord" (ibid. xxv. 21). The children were contending with one another within her womb like mighty warriors, as it is said, "And the children struggled together within her" (ibid. 22). The time of her confinement came round, and her soul was nigh unto death owing to her pains. And she went to pray in the place whither she and Isaac had gone, as it is said, "And she went to inquire of the Lord" (ibid.). What did the Holy One, blessed be He, do? Jacob took hold of the heels of Esau to make him fall, as it is said, "And after that came forth his brother, and his hand had hold on Esau's heel" (ibid. 26). Hence thou mayest learn that the descendants of Esau will not fall until a remnant || from Jacob will come and cut off the feet of the children of Esau from the mountain of Seir, as it is said, "Forasmuch as thou sawest that a stone was cut out of the mountain without hands" (Dan. 2:45). Another Scripture text says, "Vengeance is mine, and a recompence, at the time when their foot shall slide" (Deut. 32:35).
