Musar su Deuteronomio 22:19

[Likewise] one who put out a bad name (on someone else), as it is stated (Numbers 14:37), “And those who spread such calumnies about the land died of plague in front of the Lord.” And our Rabbis, may their memory be blessed, said (Arakhin 15a) [that] if the punishment for one who puts out a bad name on the land is death, all the more so for one who puts out a bad name on a fellow Israelite - who is obligated in Torah and the commandments. And it is stated (Deuteronomy 22:19), “And they shall fine him a hundred [shekels of] silver and give it to the girl’s father; for the man has put out a bad name, etc.” Behold, the verse did not mention his sin about having tried to take the life of the woman, and causing her to be killed in court with false witnesses that he brought about her [fabricated] harlotry; yet it mentioned the iniquity of putting out a bad name! For it is a greater iniquity than one seeking to squelch a life, as the pain of the shame is more bitter than death. And so did our Rabbis, may their memory be blessed, say that he is liable lashes and [a fine] for putting out a bad name, not for having sought to kill her. And our Rabbis, may their memory be blessed, said (Yerushalmi Bava Kamma 8:7) that one who puts out a bad name with words about a blemish in the family is never able to atone. For it is not enough for him to get pardoned by those still alive, as he caused the shame and disgrace of their forebears that gave him birth. And we will still add more to its explanation [when we explain] the severity of the four death penalties [of the court].

Since no individual can fulfil all 613 commandments, even at the time when the Temple is standing, we must ask ourselves how one can attain one's שלמות, perfection, both the perfection of one's body and that of one's soul. There are three reasons that some people cannot fulfil all the 613 commandments. Either a certain category of commandments applies only to a certain category of Jews, and such categories are determined at birth, or they cannot be fulfilled because certain events have not occurred during one's lifetime. A person cannot perform the commandment of the levirate marriage or the giving of חליצה, (an act demonstrating that one refuses to marry that sister-in-law) to his sister-in-law of a brother who died without issue, since such situations are beyond his control. One cannot take refuge in a city of refuge unless one had killed someone inadvertently. One cannot make the payments imposed by the Torah for having accused one's wife of not having been a virgin at the time of the wedding, unless circumstances had made such an accusation possible. The examples of all the commandments that most people are never called upon to fulfil are too numerous to list here. There is a third category of commandment which though easily capable of fulfilment, requires certain conditions, such as the affixing of a Mezuzzah on one's door post. If one dwells in a tent, this commandment does not apply since the entrance to a tent does not meet the requirements necessary to make that commandment applicable. ^{Author's comment} I have found the following interesting comment in a book called Megillat Setarim. I quote verbatim: "The mystique of the 613 commandments is that they are divided into 248 positive commandments and 365 negative commandments. Nowadays (when the Temple is in ruins, and Israel in exile), only 126 of the 248 positive commandments are capable of being fulfilled. Only 243 of the 365 negative commandments are capable of being observed. This leaves us with a total of 369 commandments that are capable of fulfilment in our day and age. This is alluded to in the sentence אני ישנה ולבי ער, (Song of Songs 5,2) "asleep” which equals 365 to which you add one for each word, making 369. As a result we are unable to fulfil 244 of the commandments. The numerical value of 244 can be expressed as מרד, (insurrection, revolt). This is to remind us that due to our insurrection against G–d's rule, we lost the Temple. Only 48 of the 126 positive commandments that are capable of being performed nowadays apply to each individual. The other 78 positive commandments need to be fulfilled only when certain circumstances occur. Many such circumstances may never occur during a person's lifetime. Similarly only 222 of the 243 negative commandments that apply in our times are capable of being observed by every individual Jew. The remaining 21 negative commandments can be observed only when certain circumstances occur in a person's life. When you combine the numerical value of the 48 positive commandments that apply to every Jew today with the 222 negative commandments each one of us is duty bound to observe, you get the numerical value of the other half of the verse mentioned earlier namely ולבי ער, i.e. 270.

How great is the power of lashon hara! For when we were in the desert, many times we rebelled against the L-rd, as in the episode of the golden calf and the like, and still their decree was sealed only because of the lashon hara of the spies alone. And we find there (Arachin 15a) that verbal imputation of an [illicit] act ["motzi shem ra"] is worse than the act itself. For one who ravishes a virgin pays a fine of only fifty silver shekels, while one who imputes an evil name [to her] is fined a hundred silver shekels, it being written (Devarim 22:19): "And they shall fine him a hundred [shekels of] silver… for he has given out an evil name [(of licentiousness)] about a virgin of Israel." And he [the imputer of the evil name] also receives stripes because of this, as it is written (Ibid. 18): "And they shall chastise him [with stripes]."
