Бамидбар 23:10 Каббала: Zohar

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. This is the significance of the words: “If he came by himself, he shall go out by himself’; the reference is to a man who refused to get married and beget children.

For, as he has made good his former omission, he is received by the Holy King, who restores him to the position intended for him. He is called a “repentant sinner”, for he comes into the heritage of his original place in the ever-flowing celestial river.¹Which is the source of all souls. There is no obstacle in the world that can stand in the way of repentance
