Chasidut zu Schemuel II 14:34

This discourse will discuss the reasons why the miracle was performed through oil. The discourse is called "Oil for Lighting": The reason why Hashem performed the miracle through oil is because the Greeks wanted to abolish the wisdom of the Torah and increase foreign wisdom, Greek philosophy. At the time of salvation, “The Jews had light” (Ester 8:16) - this refers to the Torah (Megillah 16b). Hashem performed the miracle through oil which is alluded to the wisdom of Torah, as Chazal say (Menachot 85b): “Yoav sent (a messenger) to Tekoa to bring a wise woman from there” (Shmuel II 14:2). He sent specifically to Tekoa because the oil in Tekoa was second to none, and wherever olive oil is found, wisdom is found. (As I mentioned above several times).

As it says, “And Joab sent to Tekoa [Tekoa produces fine olive oil] and brought a wise woman from there,” (II Samuel 14:2 with Menachot 85b). Because the constellation of this month is the Bucket (Aquarius) the constellation of Israel, the servant who serves with water, which is Torah, the essence of Wisdom:

But nevertheless, even when the aspect of Divinity that he had leaves him, nevertheless an imprint of Holiness is left in him through which he can strengthen himself as we have said. For without this he would remain Below, God forbid, after the Holiness leaves; and through the remaining of the imprint he strengthens himself as we have said. For that is the nature of Holiness: that even after it leaves an imprint remains behind, as our Sages of Blessed memory said, “The Shekhinah has never moved from the Western Wall” (Exodus Rabbah 2.2). And that is [the meaning of the verse], for the tzaddik falls seven times and rises (Prov. 24:16), meaning that he falls in order to be rising to an even greater level. And all of this is for a tzaddik; but someone who is not within the bounds of tzaddik, the Holy Blessed One devises plans so that the banished one will not remain an outcast (2 Sam. 14:14) and wants to draw him close to God. But because he is not attached to the Blessed Creator he falls to a place of Judgments. For there are no Judgments upon someone who is attached to the Blessed Creator, since he is attached to the Source of the Life of Lives, where there is no Judgment. But in the opposite case, one who is not attached, then [God] contracts Godself, as if it were possible, to the human, [God’s] Divinity to the place where that person is, in those Judgments that come upon him. For through this [the person] will draw closer to Blessed God and will come to the aspect of Beersheba, which is to attach to [God’s] Blessed Reverence, which is called “The Well [be’er] of Living Water,” for one who is attached to this is sated [save’ah] from all the Eternal Good.
