This week’s sedra starts with the pasuk: ויקח קרח בן יצהר בן קהת בן לוי ודתן ואבירם בני אליאב ואון בן פלת בני ראובן - “Korach, son of Yitzhor, son of Kahos, son of Levi, separated himself with Doson and Avirom, sons of Eliav, and Oin son of Peles, the offspring of Reuven” (Bamidbar 16:1). There is a famous Medrash which contrasts two types of wives - the wife of Korach and the wife of Oin ben Peles (see Sanhedrin 109b).
The Gemara writes, that Korach’s wife encouraged him to stand up against Moshe, whereas Oin ben Peles’ wife, on the other hand, counseled her husband to avoid the dispute. She said: “Listen, Oin, what are you going to get out of this? ... Either Moshe will emerge as the unchallenged leader or Korach will emerge as the leader. In either case you will be nothing more then a talmid!”
Rav Chaim Shmuelevitz explains that when most people are involved in a machlokes, they ‘lose their cool’ and lose their common sense. The fire of machlokes — picking sides, getting involved, becoming part of it — is all-powerful. It requires brilliance to overcome that tendency and instead use such a simple and down to earth approach. Maintaining common sense in moments of tension requires great wisdom.
