Midrash su Deuteronomio 13:17

We have been taught in a Baraitha R. Juda says: "If his mother was not like his father in her voice, in her appearance and her height, he cannot become a ben Sorer and Morch (a rebellious son), because it is said (Deut. 21, 12) … To our voice. Since we see that their voices must be alike, the same is the case with the appearance and height." R. Simon said: "We are taught in a Baraitha: Does the law indeed dictate that because this boy consumed a pound of meat and drank half a lug of Italian wine that his father and mother shall deliver him to be stoned? We must therefore assume that such a thing neither occurred nor ever will be, and it is merely written for the purpose to interpret it and be rewarded for it." R. Jonathan, however, said: "I myself have seen such, and have even sat on his grave." According to whom is the following Baraitha: A town that has been misled never occurred and will never be — and it was merely written only for the purpose to interpret it and be rewarded for it? In accordance with R. Eliezer, who said in the following Baraitha: A town said to be misled in which there is to be found even one Mezuzah, cannot be condemned as a misled town, because it is written (Ib. 13, 17) And all its spoils shall thou gather into the midst of the market-place thereof, nad thou shalt burn them with fire. And as there is a Mezuzah which cannot be burnt, for it is written (Ib. 12, 4) Ye shall not do so unto the Lord your God." R. Jonathan, however, said: "I have seen such and I myself have even sat on its heap of ruins."

Rabbi Yoḥanan of Tzippori interpreted the verse regarding mounds [teluliyot] of dirt. One who is foolish, what does he say? Who can completely remove this? One who is wise, what does he say? I will remove two containers during the day and two containers at night, and the same tomorrow, until I clear it all. So too, one who is foolish says: Who can study the entire Torah? Nezikin⁴⁷Bava Kama, Bava Metzia, and Bava Batra are each ten chapters long and are considered one integrated tractate (see Bava Kama 102a). is thirty chapters, Kelim is thirty chapters. The wise man says: I will study two halakhot today and two tomorrow, until I learn it all.
Rabbi Yannai said: “Wisdom is lofty to a fool” (Proverbs 24:7) – this is analogous to a perforated loaf that is suspended in the air in a room. The fool says: Who can take this down? The wise man says: Did another not suspend it? I will bring two sticks and attach one to another until I take it down.⁴⁸If one stick is not enough to enable me to reach the loaf, I will tie two sticks together. So too, the fool says: Who can learn all the Torah that is in the heart of my teacher? The wise man says: Did he not learn it from another? I will study two halakhot today and two tomorrow, until I learn all the Torah of this Sage.
Rabbi Levi said: [This is analogous] to a perforated basket whose owner hired workers to fill it with water. The fool says: What am I accomplishing? I fill it from here and it flows out from there. The wise man says: Do I not collect my wage? Do I not collect a wage from my employer for each and every barrel? So too, the fool says: I study Torah and forget it; what am I accomplishing? The wise man says: Does the Holy One blessed be He not give me reward for my effort? As Rabbi Levi said:⁴⁹The text should state: “Another matter: Rabbi Levi said” (Etz Yosef). Even matters that you see as dots [kotzim] in the Torah, they are heaps upon heaps [tilei tilim]; they have the capability to destroy the world and to render it a mound [tel], just as it says: “It shall be an eternal mound” (Deuteronomy 13:17). It is written: “Hear Israel, the Lord is our God, the Lord is one [eḥad]” (Deuteronomy 6:4); if you transform the dalet into a resh you will destroy the world.⁵⁰The word one [eḥad] will become other [aḥer], turning this affirmation of faith into a declaration of heresy. This occurs by merely erasing one small dot of the dalet, thereby turning it into a resh. “For you shall not prostrate yourself to another [aḥer] god” (Exodus 34:14) – if you replace the resh with a dalet you will destroy the world.⁵¹The verse would then state: You shall not prostrate yourself to the one [eḥad] God, which is a heretical statement. It is written: “They shall not profane [yeḥalelu] My holy name” (Leviticus 22:2); if you replace the ḥet with a heh, you will destroy the world.⁵²Profane [yeḥalelu] would become praise [yehalelu]. It is written: “I will wait [veḥikiti] for the Lord” (Isaiah 8:17); if you replace the ḥet with a heh, you will destroy the world.⁵³Wait [veḥikiti] would become strike [vehikeiti]. It is written: “Let all who breathe [tehalel] praise the Lord” (Psalms 150:6); if you replace the heh with a ḥet, you will destroy the world.⁵⁴Praise [tehalel] would become profane [teḥalel]. It is written: “They have denied the Lord” (Jeremiah 5:12); if you replace the bet with a kaf, you will destroy the world.⁵⁵“The Lord [baHashem]” would become: Like the Lord [kaHashem], which implies that the Lord also denies truths. It is written: “They have betrayed the Lord for they have begotten foreign children” (Hosea 5:7); if you replace the bet with a kaf, you will destroy the world.⁵⁶“The Lord [baHashem]” will become: Like the Lord [kaHashem], implying that the Lord betrays others. It is written: “There is no one as holy as the Lord, as there is none like You [biltekha]” (I Samuel 2:2) – Rabbi Abbahu bar Kahana said: Everything wears out but You do not wear out, “as there is none like you,” there is none to outlast you [levalotekha].

... “Moab is my washbasin…” (Tehillim 60:10) When Israel entered into their land in order to inherit it, the Holy One forbid them to conquer these three nations, as it says “Do not distress the Moabites…” (Devarim 2:9) So too regarding Edom it is written “You shall not provoke them…” (Devarim 2:5) From where do we learn that they were not to conquer the land of the Pelishtim? Because it is written “God did not lead them [by] way of the land of the Philistines for it was near…” (Shemot 12:17) The oath which Avraham swore to Avimelech was still near in time, “And now, swear to me here by God, that you will not lie to me or to my son or to my grandson…” (Bereshit 21:23) His grandson was still alive. In the future the Holy One will permit Israel to conquer all three, as it says “And they shall fly of one accord against the Philistines in the west, together they shall plunder the children of the East; upon Edom and Moab shall they stretch forth their hand, and the children of Ammon shall obey them.” (Yeshayahu 11:14) And it is translated as ‘they will join shoulder to shoulder as one to wipe out the Phillistines.’ Therefore it says “…Philistia, join me…” (Tehillim 60:10), Edom and Moav are their occupation as it says “Moab is my washbasin; on Edom I will throw my lock…” (ibid.)
