In this week's Torah portion, Egypt is smitten with a plague of darkness. Rashi relates that the darkness was so thick, the Egyptians couldn't move. They were frozen in the darkness.
Rashi asks why Hashem brought the darkness upon the land of Egypt? He answers: "Because there were amongst the people of Israel in that generation evildoers, and they did not want to go out of Egypt, and they died in the three days of darkness, in order that the Egyptians should not see their shameful downfall and say, 'They too are smitten as we are.'"
Elsewhere, Rashi informs us that four/fifths of the Jews refused to leave the exile in Egypt and perished in the three days of darkness.
Some things don't seem to change.
May the Almighty open the eyes of our brothers and sisters still frozen in the darkness of exile and enable them to see the light.
