Musar su Deuteronomio 17:17

Chazal have said (Yerushalmi Sanhedrin 2:6): "When King Solomon married the daughter of Pharaoh, transgressing (Devarim 17:17: 'And he [a king] shall not multiply for himself wives,' the yod of 'and he shall not multiply' [lo yarbeh] ascended before the Blessed L-rd and said: 'A deed of gift which is nullified partially is nullified entirely.' If Solomon nullifies me, who will fulfill me?' [That is, this mitzvah applies only to a king.] The Holy One Blessed be He answered: 'Solomon and a thousand like him will be nullified, but a letter of My Torah will not be nullified!' — whence it is seen that the Holy One Blessed be He is categorically opposed to one letter of the Torah being hefker ["abandoned"] to all. And if we ask ourselves what in the Torah has been abandoned, we find that the sin of lashon hara is hefker [i.e., not considered a sin] in the eyes of those who have not tasted the taste of Torah.
