Question about Chava and the Parsha
While at shul reading the parsha I thought of something and now it won't leave my head so I need to ask others. In Bereishit 3:16 when HaShem is describing Chava's punishment, He says that He would increase the pain of her pregnancies. Does this mean she has already given birth and now they'll hurt going forward? I know Rashi in his commentary makes a similar conclusion but my thought is more than just that. If she has given birth and the only humans are not only Adam and Chava, when they were expelled from Eden, did the children stay? The children themselves did not commit the sin their parents did. And if they witness their parents make that mistake and get punished, surely they wouldn't do the same. So ultimately my question is, did Chava have kids before the exile, did they sin too or day they stay sin free, if they are sin free were they exiled, and if they weren't exiled is it possible for them to still be in Eden today?
Edits: Someone mentioned that Adam and Chava were immortal initially and had no reason to have kids. I replied with that the first mitzvah HaShem gave to humans was "Multiply and be fruitful" right in the beginning in Bereishit 1:28, 2 chapters before Chava eating the fruit. Surely they wouldn't wait and heed His command. This to me, even strengthens the claim that Chava had kids already.
