ושאינו לשם שמים זו מחלוקת קרח וכל עדתו (אבות ה:יז)

Chazal say that the wife of ben Pelach saved him from Korach’s fight.  She told her husband that you won’t become the Kohen Gadol, so what difference does it make for you to belong with Korach or Aharon HaKohen.  Theoretically, she advised him something that is self understood.  Just when people are in midst of fighting, the flame is on and they can’t think rationally.  But she did think rational, and the pasuk says on her:”חכמת נשים בנתה ביתה – a woman’s wisdom builds her home!”
