Musar su Proverbi 29:12

A man is obligated to hide a secret that is revealed to him confidentially by his fellow, even though there is no matter of talebearing involved in revealing that secret. For there is damage to the holder of the secret [simply] by its being revealed, and it [can cause him] to abort his plan - as it is stated (Proverbs 15:22), “Plans are aborted without a secret.” Secondly - because revealing a secret is even an aberration of the ways of modesty, as he surely violates the will of the holder of the secret. And King Solomon said (Proverbs 20:19), “He who gives away secrets is a talebearer.” He means to say, if you see a man who does not control his spirit, to guard his tongue from revealing a secret - even though there is no issue of talebearing between a man and his friend in revealing that secret - this trait will bring him to go talebearing, which is from the four bad groups, given that his lips are not in his control to guard. He also said (Proverbs 11:13), “A talebearer will reveal secrets.” He means to say, do not confide a secret to someone who goes talebearing. For since he does not guard his lips from talebearing, do not trust him to hide your secret, even though you have given your words over to him in private and in confidentiality. And we have been warned by the Torah not to accept evil speech, as it is stated, (Exodus 23:1), “Do not accept a vain report.” And it is stated (Proverbs 29:12), “A ruler who listens to lies, all his ministers will be evildoers.” And our Rabbis, may their memory be blessed, explained (Midrash Tehillim 54) that when a ruler accepts evil speech and words of talebearing, his ministers will become evildoers and talebearers to find favor in the eyes of their master. And behold it is these three groups that we mentioned that they, may their memory be blessed, had in mind when they referred to the group of slanderers.
