Midrash su Isaia 29:4

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).

That the Sanhedrin were exiled a like number of times, we know by tradition. The places were as follows: from the cell of Gazith [in the Temple] to the market-place, from the market-place to Jerusalem, from Jerusalem to Yamnia, from Yamnia to Usha, from Usha [hack again] to Yamnia, (Ib. b) from Yamnia [back again] to Usha, from Usha to Shapram, from Shapram to Beth Shearim, from Beth Shearim to Sepphoris, from Sepphoris to Tiberias (and Tiberias was the saddest of them all; as it is said (Is. 29) And thou shalt be low, and shalt speak out of the earth). R. Elazar says they were exiled only six times, as it is said (Is. 26, 5) For he bringeth down them that dwell on high; the lofty city he layeth low; he layeth it low even to the ground; he bringeth it even to the dust. "Thence," remarked R. Jochanan, "they will in the future be redeemed, as it is said (Is. 52, 2) Shake thyself from the dust; arise, and sit down, etc."

As these nations that you are, etc. (Deuteronomy 18:14): This is that which is stated in the verse (Deuteronomy 28:13), "The Lord will make you the head, not the tail; you will always be at the top and never at the bottom." That there should not be lying judges and that you all be poor in Torah. [It is as you say (Isaiah 9:14), "Prophets who give false instruction, such are the tails." "You will always (rak) be at the top," you will only (rak) be few in this world, not forever. Another interpretation: "You will always (rak) be at the top (above),"When you come to ask something, you should not ask what is above, and not ask what is below, in the way that the [other] nations of the world [ask], as it is stated (Isaiah 29:4), "your speech shall sound like a ghost’s from the ground."As these nations that you are dispossessing, etc.," such that you should ask from it: This is that which is stated in the verse (Isaiah 8:19), "Now, should they say to you, 'Inquire of the ghosts and familiar spirits that chirp and moan,'" say to them (Isaiah 8:19, cont.), "Does a people inquire of its god, of the dead on behalf of the living?" The needs of the dead are done by the living. Would the needs of the living be done by the dead? "That moan," as they do not do not serve the needs of their heads. "As these nations, etc. but not like this to you." There is a story about a convert who was from Batsra. He said, "When I was a foreigner, I would ask of idolatry. Now I have become an Israelite and it is forbidden to me." What did he do? He saddled his donkey and went to a province and he did not ask of the idolatry. He entered the province and its priest was standing at the entrance of the province. When he entered, he saw them and was immediately afraid. He descended from the donkey and the donkey fled. The [people] that were standing there came down and he became frightened of them. [But] they stood him upright, supported him and said, "This old man fell." They [then] immediately brought him to his donkey, and [so] he entered in peace and left in peace. What caused him this? Because he held on to the Torah. Hence, "As those nations that you are about to dispossess listen to soothsayers and augurs, but the Lord your God did not give like this to you." There is a story about Rabbi Yannai and Rabbi Yochanan who were sitting at the entrance of Teveriya. There were two astrologers there who saw two Jews going out to their work. These astrologers said, "Those two men will go out but they will not come back, [as] a snake will poison them." Rabbi Yannai and Rabbi Yochanan heard [this]. What did they do? They sat at the entrance of the province to know if those two men would come back from their work. And they did come back and Rabbi Yochanan and Rabbi Yannai saw them. They said to the astrologers, "Did you not say that these two men would go out but not come back, as a snake would poison them?" They said, "Yes." They said [back], "Behold, they went out in peace and came back in peace." The astrologers observed them [and then] they said to them, "Tell us, what did you do today?" They said, "We did not do anything [unusual], but rather that which we are accustomed to do. We read the Shema and we prayed." They said to them, "You are Jews, the words of astrologers do not materialize with you, as you are Jews." Hence, "but the Lord your God did not give like this to you."
