Kabbalah su Levitico 12:2

"And Ad-nai said to Moshe: a woman that gives seed and births a male etc" - Rabbi Eleazar began with this verse: 'on my bed, at night, I searched [for the one my soul desires, I searched but haven't found him]' (Songs 3:1). The text should read 'in my bed', what is 'on my bed'? The congregation of Israel asked the Holy One of Blessing regarding the exile since she sits among the peoples with her children, and lies down in the dust, and because she lies on the ground she has become unfit to offer sacrifices, she said 'on my bed I consider that I feel sick in exile, and regarding this 'I asked [for] the One that my soul loves' and I will not restrain myself from Him.

A woman that gives seed' (Lev. 12:2) - we learned "a woman who orgasms first will bear a male." Rabbi Acha said: this is what we learned - that the Holy One of Blessing decrees on that drop whether it will be a male or a female, and you are saying if the woman orgasms first she will bear a male? Said Rabbi Yosi: obviously the Holy One of Blessing chooses between the drop of a male and the drop of a female, and by choosing, God decrees if it will be male of female.

For the sake of the First Human, and his coupling, detrimental to the Holy Blessed One, and regarding this we explain, when they come from above, until the Will comes before the Holy Blessed One, if the human has merited, they bring his pair, and if not, they separate her from him, and bring her to another/behind, and they give birth to children that are not proper. And regarding this it is written "My spirit will not remain in the human forever" (Gen. 6:3). What is 'My spirit'? You would expect 'his spirit' to be written, there are two spirits, when the pairs go out, they do not remain as one, and regarding this it is written 'and she gives birth to a male' (Lev. 12:2), and this does not include both male and female, according to the ways of the world, as we brought this about.
