This is as written, “As we have heard, so have we seen…” (Ibid. 9), none of them endured, but she, Malchut, exists now in the aspect of the male that dwells with her. This is the meaning of, “and Hadar reigned in his place, and the name of his city was Pa’u; and his wife’s name was Mehetavel, daughter of Matred, daughter of Mei-Zahav” (Bereshit 36:39), surely Mei-Zahav, as we explained in the Gathering.
In the book of Aggadah of Rav Hamnuna Saba we have learned that “Hadar reigned in his place” is certainly the goodly (Hadar) tree, that is, Yesod called the goodly tree, as said, “the fruit of the majestic (hadar) tree” (Vayikra 23:40); wherein Malchut is called fruit and Yesod the tree Hadar. “…and his wife’s name was Mehetavel,” as said, “branches of palm trees” (Ibid.). This is Yesod, referred to in plural, because it is written, “The righteous man flourishes like the palm tree” (Tehillim 92:13), meaning that it does not flourish without the female, because a palm tree consists of male and female. Therefore, it is written, “and his wife’s name was Mehetavel.” This Malchut is called the daughter of Matred, which means she is the daughter of that place that everyone is busy (tarud) trying to attain, called father, that is, Chochmah. It is also written, “Man cannot know its price; nor is it found in the land of the living” (Iyov 28:13). Thus, everyone strives to attain it. According to another interpretation, she is a daughter of the mother, Binah, whence judgments are roused that bother (matridim) everyone. Hence, she is called the daughter of Matred. She is “The daughter of Mei Zahav” because she receives from both sides that illumine in two ways, with Chesed and with judgment, that is, from right and left. The right represents Chesed and is called Mei (water) and the left represents Chochmah and is called Zahav (gold), that is, Mei Zahav (gold water).
