He sees not sin in Jacob, nor does He behold iniquity in Israel (23:21)

Rabbi Israel Baal Shem Tov once encountered a preacher who was forever berating his listeners for their sins. In the most graphic terms he would describe the nature of the evil in the heart of man and the terrible punishments in store for his sinful audience.

"Tell me',' the Baal Shem Tov asked the preacher, "how do you know so much about evil, considering that you have never tasted sin yourself?"

The preacher was puzzled. "How do you know that I haven't sinned?"

"But my dear friend, I am sure you would have discussed your own sins, if you had any, before recounting the sins of others."
