Left in the Dark
Regarding some of the makkot the Torah specifically says the Jews will be spared, the Torah itself doesn't say anything about the Jews being spared of the other plagues. The Emet L'Yaakov says that some Jews refused to leave because it wasn't time to be redeemed yet (it hadn't been 400 years of servitude yet) and wouldn't leave despite all the signs to the contrary. They were the ones who died during Choshech.
