Rabbi Shimon [bar Yochai] described the famous solidarity of the Jews in the following parable: In a boat full of passengers, one of them began to drill a hole in the bottom that was beneath where he was seated. The other passengers exclaimed, "What are you doing?" He answered, "What is it to you? I am drilling in my own space." The other passengers replied, "It is true that it is in your own place, but when the water begins to enter the boat, we, too, will drown." In like manner, when a Jew does wrong, this has repercussions on all Jews.
I thought this was relevant in light of events in Israel over the past 10 days.
