Impeding The Redemption

I heard from my teacher and father-in-law, who was the chief disciple of Rebbe Yechiel Michal of Zlotchov, that once when the Baal Shem Tov was traveling on the road, he stepped into a wooded area to pray the afternoon prayer. His disciples were dumbfounded to see him hitting his head against a tree, crying and screaming. Afterward, they asked him what had happened. He explained that he had seen, with divine inspiration, that in the generations before the coming of the Moshiach there would be a multitude of rabbis, and that they would be the very ones who would impede the redemption.
