Kabbalah Mazmur 19:1: Zohar

But should he not be found worthy to procreate even after the Jubilee, he is made as though he were not, having been mercifully returned to this world and yet refusing the opportunity of reparation which was offered to him: “If he came by himself (be-gapo), he shall go out by himself (v. 8), meaning: “If he enters this world single, without. offspring, not having previously desired the engendering of children, and even now leaving this world single, he departs even as a stone which is thrown from a sling, until it reaches the place which is called “the mighty rock”, into which he enters. As soon as he is there, the breath of him who is the Single one (Samael), who had to be separated from his feminine counterpart (Lilith), and who walks after the manner of a serpent, breathes on him, and straightway he leaves that mighty rock and, wandering lonely forth, begins to roam the world until he shall find a “redeemer” through whose agency he can return to this earth.
