Kabbalah do Samuela II 23:15

A different explanation for the verse, "Drink water out of your own cistern," is that it refers to King David, who wrote: "O that one would give me drink of the water of the cistern of Bethlehem" (II Shmuel 23:15). Here, the words, "running water," refer to Abraham, and "out of (lit. 'from the midst')" refer to Jacob, who is in the center. "Your own well" signifies Isaac, who is called "well of living water." Thus, in this verse, we find a reference to both the sacred Chariot of the Patriarchs, and of King David, who joined them.
