I don't dispute that what you are saying is what rabbinical Judaism says. I dispute that it is Jewish. The belief in the pre-existence of the souls is a pagan (Greek and Persian) belief that was added to Pharisaical Judaism, and survives to this day in its direct offshoot, rabbinical Judaism and, apparently, in some corners of various Protestant sects as well.
This is what Jewish Encyclopedia has to say about this:
This belief is, therefore, not "intrinsically" Jewish but pagan. Thus, the JE continues:
Clearly, then, modern Judaism is a mixture of old Judaism and (Greek, Persian) pagan beliefs.
What fascinates me is that some Protestant groups will adhere to this type of (rabbinical) Judaism rather than to Christian beliefs which regardless whether based on traducianism or creationism agree that the soul does not pre-exist the body.
Rabbinical Judaism also says that the souls of the Gentiles are created by the demons.
Do you believe that too? Are some Protestants unsure if they are Christians or Jews? Or do they consider themselves a little bit of both?
Jacob had an additional soul

I don’t know what kind of Christian you are, but Jesus is the true vine. As to where souls are and come from it’s not something that concerns me. I was pinged over here and gave an opinion from what I know.
In reading through the Jewish Encyclopedia I wouldn't make too much out of your quote as it is built upon a bunch of rabbinical traditions. (ouch!)
However, I couldn't help but noticing the Jewish view of the soul on another site:
