Kabbalah do Rodzaju 36:39

Come and behold, Rabbi Yochanan ben Zakai used to say that 300 legal decisions are derived from the verse, "and his wife's name was Mehetabel, daughter of Matred, daughter of Mezehab" (Beresheet 36:39). This he revealed only to Rabbi Eliezer, who was with him. That shows how many secrets of the Torah are in every deed in the Torah. In each word, there is wisdom and true doctrine. Therefore the words of the Torah are holy words, by which to conceive wondrous things, as it is written, "Open you my eyes that I may behold wondrous things out of Your Torah" (Tehilim 119:18).

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.
