According to the Chasam Sofer, the most difficult command in the Torah
is, "והייתם נקיים -
מישראל". It's next to
impossible to fulfill this command.
The Chasam Sofer (Shut 6 : 59) writes. "There
are two obligations
1) To come clean from Hashem 2) from Bnei
It is much easier
to fulfill the first obligation than the second one.
The punishment on the
second obligation is also much greater.
can have a person doing something which is Halachicly correct, but isn't careful and some "שותי
שכר" (beer drinkers) mistakenly accuse him of wrongdoing, such a person has
not fulfilled hisobligation of והייתם נקייםמישראל.
It is almost
impossible to fulfill this obligation. It is very likely שלמה המלך had this in mind when he wrote אין צדיק
We find the
Bnei גד etc. followed Moishe Rabbeinu's advice and fought along with the other שבטים for 14 years. They were
punished to be sent to גלות before the rest of כלל ישראל,
because they haven't fulfilled 100% the obligation of והייתם נקיים ."
