A self-fulfilling prophecy
ויקח קרח בן יצהר בן קהת בן לוי ודתן ואבירם וגו’
Korach the son of Yitzhar the son of Kehas the son of Levi took (something), and Dasan and Aviram, etc.
This week’s parsha details the rebellion of Korach. He challenged the leadership of Moshe and Aharon, convincing a group of the greatest sages of Israel to join his cause. Moshe challenged this band of rebels to a test to determine who was the true prophet of Hashem. The result was that the sages who joined Korach died in a fire, while Korach and his entire family were swallowed up alive into the earth, to live there until the end of days. The parsha starts with the awkward phrase ויקח קרח, Korach took. The verse doesn’t specify what exactly it was though that he took. There are various explanations among the commentators. Reish Lakish in the gemarra says that it means that לקח מקח רע לעצמו, he acquired a bad purchase for himself.
