Musar su Genesi 33:11

I have already hinted that Jacob, who referred to himself as possessing כל, "all," in Genesis 33,11, is similarly described by that term in our grace prayer. What is meant is his remaining totally alive, seeing all his children continued to live according to their father's tenets. Jacob was also called איש, and our sages relate that whereas Jacob did not die, Esau did die (Taanit 8). Esau had said of himself in Genesis 25,32 that he was headed for death. Jacob's ability to remain "alive," חי, began with Sarah, who was not attached to the קליפה, and through whose son, ביצחק, one side of such pollutants was already removed, i.e. מיצחק, hence the description of his blessing as מכל. The terms בכל-מכל-כל, refer to elimination of the pollutants in ever-increasing measure. Abraham therefore is at the bottom of such a chain whereas Jacob is at the top, and thus was called חי.
