זוהר שמות — דף קיד ע”ב

In the fourth exile it is said to Moses: "Go, descend" for the sake of the fallen bride, and immediately upon descending for her, she will rise. The Torah was revealed to Moses more than to all Israel, like the well-waters that rose to him. This well is full and its waters do not flow out; all the world's waters enter into it. The commandment of the cities of refuge was given to Moses because of the Egyptian he slew, to protect Israel from Na'ama, Agrat and Black Lilith. In the future the Holy One blessed be He will engrave His Name in Moses, whose thought is yod-heh-vav-heh, and Moses ascended to Binah because he entered behind her in repentance to bring her up from exile.
