260. He began the discussion by quoting the verse, "And these are the children of Tziv'on; both Aya and Ana: this is Ana who found the Yemim in the wilderness" (Beresheet 36:24). This verse has already been explained, yet come and behold, these are not those mentioned in the verse, "The Emim dwelt there in times past ...but the children of Esau succeeded them" (Devarim 2:10-12).
261. But in the verse, "who found the Yemim in the wilderness," Yemim is spelled defectively, WITHOUT THE LETTER YUD, WHICH IS AN INDICATION OF WANT, because THE DESCENDANTS OF CAIN -- after he was driven from the face of the earth -- are strange creatures, as it is written, "Behold, You have driven me out this day from the face of the earth; and from Your face I shall be hid" (Beresheet 4:14), and "and dwelt in the land of Nod" (Ibid. 16). This has already been explained.
263. They kept on spreading from that side of Cain, THAT IS, BEING HIS DESCENDANTS, clothed by that side yet without TANGIBLE EXISTENCE. Yemim is THEREFORE spelled without a Yud, for they are disowned by both days, THAT IS, BY BOTH FRIDAY AND SHABBAT, BECAUSE THEY WERE CREATED AT SUNSET. They may be seen by men -- THAT IS, DESPITE BEING GHOSTS, ONCE A DAY THEY DON A BODY. ANA found THE SPIRITS CALLED YEMIM, and they taught him how to bring bastards into the world, THAT IS, BY MATING A DONKEY AND A HORSE SO THEY WOULD ISSUE A MULE. They haunt the mountains and don a body once a day, then strip themselves AND REMAIN BODILESS.
