Acharei Mot-Kedoshim 5775

Of the many commandments in Parshas Kedoshim, the Torah warns us about cheating in business and immoral relations. The Gemara in Bava Basra (88b) compares the two sins and concludes that cheating is business is worse. How so? The Gemara answers that one can do teshuvah for immoral relations, but cannot do teshuvah for cheating in business. Rashi and Tosafos add that when one steals from a community, it is impossible to return money to each individual and therefore an incomplete teshuvah.

Acharei Mot-Kedoshim 5772

In the second Parsha we read, Kedoshim, Hashem tells Moshe to "speak to the whole congregation of Israel" (19:2). The Chizkuni explains that this Parsha was spoken the nation as a group (as opposed to small, seperate groups). The reason for this is because Kedoshim includes many Mitzvos that parallel the 10 Commandments. Why say them here? Because Bnei Yisroel thought in order to stay established in Israel, they only needed to refrain from the prohibitions of immoral relations as this was the warning at the end of the list. The Torah was telling them that there are other Mitzvos that must be kept to stay planted in the land. One can suggest that the Chizkuni uses the example of the 10 Commandments to stress the importance of keeping the "fundamental" Mitzvos as many note that the they encompass all 613.
