Thank you both for your responses.

Yes, that is such a frightening thought, that those woman would have suffered like that!

Did that horrible practice continue all the way up until the day that Noah entered the ark?

If their mothers died when they were born, then were those newborn giants raised at all by the fallen angels?

Or did those fallen angels simply spawn them, and leave those newborn giants to grow and fend for themselves?

If so, they could have grown to be very terrible beings, full of rebellion, hatred, and violence.
