Lying
The shul Rav told his congregation, "Next Shabbos I plan to speak about
lying. To help everyone better understand my drash please read all
66 verses on the story of Lavon in Genesis chapter 33.
The following Shabbos, as the Rav prepared to give his drash he asked
for a show of hands from his congregation on how many members had read
all 66 verses of Genesis 33. Almost ever hand went up. He smiled and
said, Genesis Chapter 33 has only fifty four verses. Now let us with
the discussion on the sin of lying."
