Midrash su Deuteronomio 28:1

And it shall be if you truly listen (Deuteronomy 28:1): This is that which was stated in the verse (Song of Songs 1:3), "Your ointments yield a sweet fragrance, your name is like finest oil." Rabbi Yannai said in the name of Rabbi Shimon, "You gave the aroma of commandments to the early ones: To the children of Noach, seven [commandments]; Avraham arose, You gave him circumcision; to Yaakov, You gave [the prohibition of eating] a limb from a living [animal. But] when we stood in front of Mount Sinai, you gave us commandments like a man pouring from the mouth of a barrel." "Your name is like finest (turak) oil." What is [the meaning of] "turak?" Rabbi Levi said in the name of Rabbi Shila, "That bring alacrity to the one that does His will. And the expression turak can only be a weapon, as it is stated (Genesis 14:14), 'and he armed (vayarek) his retainers.'" Another interpretation [of] "Your name is like finest (turak) oil." The Torah is compared to oil and it is compared to water. To water, as it is written (Isaiah 55:1), "Ho, all who are thirsty, come for water." Just like the world cannot stand without them and a man purifies himself in them, so too can the world not stand without Torah, and the Torah teaches man how to purify himself. And just like water, a man does not plant a tree and does not build a house if he has no water, so too can the world not stand without Torah. And just like water is life to the world, so too is Torah life to the world. Just like [with] water, anyone who does not know how to swim in it will cause himself to be lost from the world, so too anyone who is not able to find words of Torah is lost from the world. Just like water can be drawn to any place one wants, so too is the Torah drawn in all of the world. Just like water is not preserved in silver containers nor in gold containers but rather in ones of clay, so too is Torah not preserved in the haughty, but in one with a humble spirit. And Rabbi Acha says, "'But from where (which can also be read as, from nothing) can wisdom be found.' What is [the meaning of] 'from nothing?' From those who make themselves like nothing." And just like this water no one supervises [to demand a price], so is the Torah. You find that it is [also] compared to honey, as it is written (Psalms 19:11), "sweeter than honey, than drippings of the comb." Just like honey is not polluted, so is the Torah not polluted, as stated (Proverbs 8:8), "All my words are just, none of them perverse or crooked." And the Torah is compared to oil. Just like oil brings light to the whole world, so too is the Torah light to the world. And just like this oil is crushed and the more it is crushed, the better it is; so too [with] the Torah, [the more] one [exerts] himself upon it, the better it is to its Owner. You find that with all liquids, you can counterfeit them and put other liquids in them; but [with] this oil, he [can] put it in any liquid that he wants, and it rises to the top. So too is Israel; even if they are placed at the bottom, behold they are like this oil that [rises] to the top, as stated (Deuteronomy 28:1), "the Lord your God will set you high above all the nations of the earth."

Another matter, “by the fragrance of your good oils,” Rabbi Aḥa [said] in the name of Rabbi Tanḥum ben Rabbi Ḥiyya: There are two oils, the oil of priesthood and the oil of kingship.¹⁴³The plural term oils in the verse refers to these two positions. Kings and High Priests were anointed with special oil during their inaugurations. The Rabbis say: There are two Torahs, the written Torah and the Oral Torah.
Rabbi Yudan said: “Your name is like poured oil [shemen],” oil improves on anyone who engages in the greatness [shamna] of the Torah. This is [consistent with another] opinion of Rabbi Yudan, who said: “The yoke will be broken due to the oil” (Isaiah 10:27). The yoke of Sennacheribwas broken due to Hezekiah and his associates, who were engaged in the greatness of Torah.
Another matter, “your name is like poured oil,” just as this oil is bitter at its outset and sweet at its culmination, so too, “your beginning may be small, but your end will soar very high” (Job 8:7). Just as this oil improves only by means of crushing, so too, Israel repents only by means of crushing. Just as this oil does not mix with other liquids, so too, Israel, does not intermingle with the nations of the world, as it is written: “You shall not marry them” (Deuteronomy 7:3). Just as this oil, a full cup does not cause a drip like other liquids, so too, matters of Torah do not dislodge matters of cynicism.¹⁴⁴If a drop of oil falls into a full cup of a different liquid, since the oil floats to the top, it is the oil that overflows rather than the other liquid. Similarly, if one’s heart is full of cynicism and one hears words of Torah, the Torah will not penetrate (Midrash HaMevoar). Just as this oil, when you have a cupful of oil in your hand and a drop of water falls into it, a corresponding drop of oil is dislodged, so too, if a matter of Torah enters the heart a corresponding matter of cynicism is dislodged, and if a matter of cynicism enters the heart,¹⁴⁵This is the case if one’s heart has some cynicism, but is not saturated with cynicism. a corresponding matter of Torah is dislodged. Just as this oil brings light to the world, so too, Israel is light for the world, as it is stated: “The nations will walk by your light” (Isaiah 60:3). Just as this oil is superior to all liquids, so too, Israel is superior to all nations, as it is stated: “The Lord your God will place you supreme” (Deuteronomy 28:1). Just as oil does not produce a sound,¹⁴⁶When poured from one vessel to another. so too, Israel does not produce a sound in this world.¹⁴⁷They do not respond to those who antagonize them, but rather, accept in silence. But regarding the World to Come it is written: “You will be brought down and you will speak from the ground” (Isaiah 29:4).¹⁴⁸This will culminate “with thunder and with earthquake and great noise, storm and tempest and the flame of a consuming fire” (Isaiah 29:6).

And it shall be if you listen to listen (Deuteronomy 28:1): If you listened a little, your end will be to listen much. Another interpretation: You will make your studies heard in front of the Holy One, blessed be He. When will you make your studies heard? Rabbi Yehudah says, "At the time that he comes to part from the world, as it is stated (Ecclesiastes 12:13), 'The end of the matter, everything is heard.'" And Rabbi Meir says, "until he completes his soul, as stated (Job 10:22), 'gloom and not arranged,' as he arranges his study." Another interpretation: "If you surely listen," your prayer will be heard, like Choni the Circle-maker. At the time that Israel required rain, they went into him and said to him, "Pray for us, as we need rain." Immediately, he drew a circle and stood inside it, to fulfill that which is stated (Habakuk 2:1), "I will stand on my watch." The rain began to drizzle. He said, "This is not what I requested, but rains of desire, blessing and freewill." The rain [then] began to fall in its accustomed way. What caused him to be one who prays, such that the Holy One, blessed be He listens to his prayers? [It was] because he listened to the words of the Torah. Another interpretation: If you listen in this world, you will listen [to it] in the world to come from the mouth of the Holy One, blessed be He. Rabbi Yonah the father of Rabbi Manna said in the name of Rabbi Levi who said in the name of Rabbi Abba, "The Torah was not supposed to have been given to Israel in this world. Why? Because everyone will learn it from the mouth of the Holy One, blessed be He, in the future, in the world to come. [So] why was it given to them in this world? So that when the Holy One, blessed be He, comes to teach them in the world to come, everyone will know in what section He is occupied." Therefore, if you listen in this world, you will listen in the world to come from the mouth of the Holy One, blessed be He. Another interpretation: If you merited to listen to words of the Torah that were given with many voices, you will merit to hear that voice about which it is written (Jeremiah 7:34), "the voice of gladness and the voice of joy." Another interpretation [of] "if you listen to listen": If you have listened to the voice of your teacher, your end is that others [will] listen to you. "To guard to do" (Deuteronomy 28:1). You should only study in order to do. Rabbi Yochanan said, "Anyone who studies [Torah] but does not do [what he studied], it would have been better had his placenta turned over his face (died in the womb). But if you merited to guard and to do, 'the Lord your God will set you high above (elyon)' (Deuteronomy 28:1)." Rabbi Levi said, "What is [the meaning of] elyon? It is like this thumb (alyon). If you merited, behold you will be above the four fingers, 'and the Lord your God will set you high above,' on condition. But if not, 'the stranger that is in your midst will rise higher and higher' (Deuteronomy 28:43)." "Blessed shall you be in your coming" (Deuteronomy 28:6), on condition [that it is] in your coming to the synagogues and study halls; "and blessed shall you be in your going," from the synagogues and study halls. "You shall be blessed in the city and you shall be blessed in the field" (Deuteronomy 28:3). It should have said, "You shall be blessed in the field and you shall blessed in the city," as it is from what he brings in from the field that he is blessed in the city. Rather what do we learn to say [from,] "You shall be blessed in the city and you shall be blessed in the field?" If you have come to the commandment in the city, do not say, "I was only commanded in the field to extract the priestly tithes and the [other] tithes outside." The Holy One, blessed be He, said, "Open your hand [to give tithes] also in the city." Another interpretation: "You shall be blessed in the city," with the commandments that you do in the midst of your house in the city, such as sukkah, mezuzah and parapet. "You shall be blessed in the field," [with the commandments that you do in the field], such as [leaving] gleanings, forgotten sheaves, and the corner [of the field]. Another interpretation: A man should not say, "If the Holy One, blessed be He, had given me a field, I would have extracted tithes from it. [But] now that I do not have a field, I will not give anything." The Holy One, blessed be He, says [in response], "See what I have written in My Torah, 'You shall be blessed in the city,' for those living in the city; 'and you shall be blessed in the field,' for those that have fields." "Blessed shall be your basket" (Deuteronomy 28:5). These are the first-fruits that you you bring up to Jerusalem, as it is stated (Deuteronomy 26:4), "And the priest shall take the basket from your hand." "And your kneading bowl" (Deuteronomy 28:5), that is the challah tithe. "[Blessed shall be...] the calving (shegar) of your herd" (Deuteronomy 28:4). Rabbi Yehudah bar Shalom said, "That they shall be moving (shegurin) and coming out [effortlessly] like [from] the mouth of a box; 'and the lambing (ashterot) of your flock' (Deuteronomy 28:4), that they should be as strong as boulders (ashterot)." Another interpretation: "You shall be blessed in the city," this [refers to] Jerusalem, which is called a city, as it is stated (Lamentations 2:15), "Is this the city that they said was the perfection of beauty?" "And you shall be blessed in the field," this [refers to] Zion, as it is stated (Jeremiah 26:18), "Zion shall be plowed for a field." And when will the Holy One, blessed be He, show this blessing to Israel? When Jerusalem is rebuilt and the exiles are returned within her, as it is stated (Psalms 133:3), "As the dew of Hermon which runs down on the mountains of Zion, for there the Lord commanded the blessing, life forever." [May it happen] speedily in our day, Amen!
