Kabbalah zu Ijow 3:3

Go and see: in the moment that a person comes to make oneself holy to pair oneself with one's female, with a holy friendship/connection, a holy spirit is stirred in that person, that includes male and female. And the Holy One of Blessing alludes to the appointed agent to the pregnancy of human beings, and gives into the agent's hand that spirit and informs the agent where the agent should place it. For instance, it is written: "the night said: 'a male has been conceived'" (Job 3:3). The night said, to that appointed agent, a male was conceived from so-and-so, and the Holy One of Blessing informed the agent about that specific spirit. Everything that was informed to the agent, the agent keeps.
