Parshas Balak: Dubno Magid - Bilam, The Magid Meisharim Of Aram
There was once a Magid whose regular audience were a very bad crowd who ate treifos and were thieves. He would always give them sharp and fiery mussar about their bad way and implore them to change.
One day this Magid found himself in a Chashuvah Kehila in Warsaw and they asked him to speak. So he got up and gave his usual fiery drasha warning the people to stop eating Treif and other heinous crimes. The crowd was astounded. What did he want from them?
The Dubno Magid uses this Mashal to explain the pasuk (Balak 23:7), "Min Aram Yancheini Balak Melech Moav... Licha Ara Li Yaakov". Bilam says to Balak what did you expect from me? I am a wonderful Magid in Aram where the people are liars and cheaters. How am I supposed to know how to speak about Bnei Yisroel the Am HaKadosh?
