Musar su Genesi 23:6

Ephron, or rather the people of his town also hinted at that fact when they said in 23,15 נשיא אלוקים אתה בתוכנו, "you are a prince in our midst." They realized that while Abraham represented the essence of what was good, Ishmael represented the קליפה on the "right," Esau that on the "left." We here view grandchildren as being in the same class as children. Isaac, who is described in the grace after meals as the recipient of the blessing מכל, has only one קליפה, Esau attached to him. Jacob, on the other hand, is totally free of any קליפה sticking to him. He represents the tree of life in the centre of the garden.

When the sons of Chet addressed Abraham by saying: "You are a prince of G–d in our midst" (Genesis 23,7), what they meant was that the personality of Abraham had made a deep impression on their תוכיות, internality. They felt that their own spiritual roots had become purified through having an Abraham in their proximity. They were convinced that this augured well for their future and eventual salvation, and they thanked Abraham. When our Bereshit Rabbah 43,5 explains the words עמק שוה in Genesis 14,17, by saying that all the nations agreed (השוו) to crown Abraham there as their king, this describes Abraham as being freed, set apart from the קליפות. Abraham personally represents the spiritual level of ישראל; he achieved a higher level than all the other patriarchs. The statement that his name was ישראל indicates his spiritual level as being on a very high plateau enabling him to penetrate to the most rarefied Celestial Regions. The name אברהם, on the other hand, describes his being the (spiritual) father of a multitude of nations, כי אב המון גוים נתתיך, something that was acknowledged when the sons of Chet said שמענו אדני, נשיא אלוקים אתה in 23,6. He had also been called Abram, for it was still at that time that Ishmael issued from him. We see that the dimension of אב המון already began to take practical form while Abraham was still Abram. This dimension was reinforced with the birth of Isaac, who in turn produced an Esau who incorporates all the קליפות.
