Midrasz do Przysłów 8:8

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."
