PB, re: Daniel 2:43.... bzzzz - sorry, does not match.
1 - This is prophecy of the Roman empire. It collapsed in part because as it spread, the control became disjointed due to incompatibility within the government structure because of intermingling with the captured nations.
2 - Mingling with the "
seed of men" is not the same activity as "angelic seed" impregnating human women, unless we now have female-anatomy-equipped angels.
