Korah (son of Izhar), Dathan and Abiram (sons of Eliab), and On (son of Peleth) dared to challenge Moses. (Korah was a descendant of Kohath and Levi. Dathan, Abiram, and On were descendants of Reuben.)
Yet, in a similar way, the people who slipped in among you are dreamers. They contaminate their bodies with sin, reject the Lord’s authority, and insult his glory.
