801. Rabbi Yehuda opened the discussion with the verse, "And Jacob made an end of commanding his sons" (Beresheet 49:33). HE ASKS, It says "commanding," but wouldn't one expect 'blessing?' HE REPLIES, He commanded them to be attached to the Shechinah, and commanded them concerning the cave, which is close to the Garden of Eden, where Adam is buried.
802. Come and see, this place is called Kiryat Arba (lit. 'city of four') because four couples were buried there: Adam and Eve, Abraham and Sarah, Isaac and Rivkah, and Jacob and Leah. There is a difficulty here. We learned that the Patriarchs are a Holy Chariot, yet a Chariot consists of no less than four. We also learned that the Holy One, blessed be He, joined King David with THE PATRIARCHS, and they formed a complete Chariot OF FOUR. The meaning of: "The stone which the builders rejected has become the head stone of the corner" (Tehilim 118:21) is that King David joined them and formed with them a complete Chariot. David was then supposed to be buried with the Patriarchs so together with him it will be a city of four. Why was he not buried with them?
803. HE REPLIES, A place was prepared for King David, Zion, YESOD OF ZEIR ANPIN, with which to be united as one; and Adam was buried with the Patriarchs. They were buried with him, since he was the first king, from whom kingdom was removed and transferred to King David. King David lived with Adam's days, for it was decreed that Adam should live a thousand years, but seventy were removed from him to form King David's life and he gave them to him. ADAM WAS THEREFORE CONSIDERED TO PERTAIN TO MALCHUT, AND HE COMPLEMENTED THE CHARIOT OF THE FATHERS TO A FOURSOME. OTHERWISE, how could the Patriarchs rise TO HAVE A COMPLETE CHARIOT before the time of King David? OF NECESSITY DID ADAM COMPLEMENT THEM. DAVID WAS NOT BURIED WITH THEM, but merited a place worthy of him, WHICH IS ZION. Hence, he was not buried with the fathers.
804. Moreover, the Patriarchs dwell in a male place, MEANING, THEY ARE CHESED, GVURAH AND TIFERET OF ZEIR ANPIN, WHICH ARE MALES. David, WHO IS A CHARIOT TO MALCHUT, is in a female place. Hence the fathers were buried with their wives, and David was buried and attached to a male place, ZION, each as befits him.
