Kabbalah su Genesi 26:78

{Elijah} opened and said, 'Faithful Shepherd, the Holy One, blessed be He gave this bride of yours, [ this refers to Malchut/Kingship] to Abraham to bring up for you. And since he kept her she is called his daughter. This is what is meant by the saying that Abraham had a daughter whose name was 'Bakol (Eng. 'in all')'. By her he observed the whole Torah even the Eruv Tavshilin (an action allowing one to cook on holiday for Shabbat). This is the meaning of, "and kept My charge" (Genesis 26:5). And he brought her up, as written, "And he brought up Hadassa" (Esther 2:7). And the Holy One, blessed be He, blessed him for her sake, as it is written, "and Hashem had blessed Abraham in all things (בַּכֹּל)" (Genesis 24:1). He brought her up with every good virtue and was charitable to her. He raised her to greatness, with the quality of kindness (Chesed) of Abraham. His house was, for her sake, wide open to do kindness to all the people of the world.

"And there was a famine in the land, beside the first famine that was in the days of Abraham" (Gen. 26:1). Rabbi Abahu opened the discussion with the verse, "While the king was reclining at his board, my spikenard sent forth its fragrance" (Shir Hashirim 1:12). We learned that the righteous will pass through four eras and four times, each different from the other. During the first, knowledge will increase in the world, and the righteous will conceive what they have not conceived in this world. As we have learned from Rabbi Pinchas, in the future, the perception of the righteous will be greater than that of the ministering angels, as it is written, "as the waters cover the sea" (Isaiah 11:9). During the second time, you shall be occupied. (End of Midrash Hane'elam)

"And there was a famine in the land..." (Gen. 26:1). Rabbi Yehuda opened the discussion with the verse, "Hashem tries the righteous, but the wicked and him who loves violence His soul hates" (Tehilim 11:5). How orderly and right are the deeds of the Holy One, blessed be He, and all He does is according to justice and truth, as it is written, "He is the Rock, His work is perfect" (Devarim 32:4).

And then Isaac, of whom it is written, "And there was a famine in the land..." (Gen. 26:1). And Isaac went to Gerar. From there, he later ascended peacefully. And so all the Righteous are tested by the Holy One, blessed be He, to raise their heads in this world and in the World to Come.

"And the men of the place asked him of his wife; and he said, 'She is my sister" (Gen. 26:7), that is, just like Abraham said. For the Shechinah was with Isaac and his wife, and he said of the Shechinah, as it is written, "Say to wisdom, 'you are my sister'" (Mishlei 7:4). Thus, he was strengthened and said, "She is my sister." Abraham and Isaac deserved (to say this). This is assuredly so because of the verse "My sister, my love, my dove, my undefiled" (Shir Hashirim 5:2). (They) were therefore worthy of saying "She is my sister." Thus, the Righteous were strengthened by the Holy One, blessed be He.

"And it came to pass, when he had been there a long time with Rivkah his wife" (Beresheet 26:8): "with (Heb. et) Rivkah his wife," precisely, which alludes to the Shechinah that was with Rivkah, because Et ('with'), as we know, is the name of the Shechinah. Another explanation asks if we could possibly conceive of Isaac performing his marital duties during the daytime. We have learned that the children of Yisrael are holy and abstain from cohabitation in the daytime. Therefore, how could Isaac, who was holy, cohabit during the day?

Assuredly Abimelech was wise and looked at the wisdom of the stars, that is called a 'window', as it is written here, "out at a window" (Beresheet 26:8), and elsewhere, "The mother of Sisra looked out at a window" (Shoftim 5:28). As there (refers to) astrology, so here to astrology. And he saw there that it was not as Isaac said, but that he surely was sporting with her, and she was his wife. Then, "Abimelech called Isaac" (Beresheet 26:9) Rabbi Yosi said that it would have befitted Abimelech to do this to Isaac, as he did to Abraham, were it not for the Holy One, blessed be He, who reproved him earlier.

"And Abimelech charged all his people, saying, 'He that touches this man or his wife shall surely be put to death'" (Beresheet 26:11). Come and behold, how long had the Holy One, blessed be He, refrained from avenging the wicked, for as a result of the good Abimelech did with the first Patriarchs, the children of Yisrael did not rule over the Philistines until generations later. Abimelech did well to act properly toward Isaac, as he said (to Abraham), "Behold, my land is before you, dwell where it pleases you" (Beresheet 20:15).

Rabbi Yehuda said, Woe to the wicked, whose generosity is not complete. Come and behold, Efron first said, "my lord, hear me, the field I give you, and the cave that is in it" (Beresheet 23:11). Later he said, "four hundred shekels" (Ibid. 14), and then, "and Abraham weighed to Efron current money with the merchant" (Ibid. 16). Here too, it is written at first "Behold, my land is before you,". Then he said (to Isaac), "Go from us; for you are much mightier than we" (Beresheet 26:16). Rabbi Elazar said to him, This is the benevolence Abimelech had for Isaac. He took nothing from him and sent him away with his money and possessions. Then, he went after him to make a covenant with him.

"And he removed from there, and dug another well..." (Beresheet 26:22). Rabbi Chiya opened the discussion with the verse, "and Hashem shall guide you continually, and satisfy your soul in drought, and make strong your bones" (Yeshayah 58:11). This verse had already been explained, but by this verse the faithful were strengthened, for it promises them the World to Come. "And Hashem shall guide you continually" in this world and the World to Come. "And Hashem shall guide you." Because he said, "And Hashem shall guide you," why add the word "continually (Heb. תָּמִיד)?" For this hints at the daily offering (lit. 'continue') made at dusk that receives its strength from underneath Yitzchak's arm. How do we know that? From David, as it is written, "He leads me in the paths of righteousness for His name's sake" (Tehilim 23:3). Just as the word "leads," spoken by David, means the illumination of the left, as it is written, "in the paths of Righteousness," which is a name of the Nukva when she shines from the left, here too when it says "guide," it alludes to the illumination of the left.

"And he called the name of it Rechovot" (Beresheet 26:22). For this reason, its springs will spread on all sides, as it is written, "So will your spring be dispersed abroad, and streams of water will flow in the broad places (Heb. רְחֹבֹת)" (Mishlei 5:16). For this reason, "he called the name of it Rechovot."
