Musar su Proverbi 28:12

And King Solomon, peace be upon him, spoke about the matter of repentance and specified this topic. And he surely opened his words and said (Proverbs 28:12), "When the righteous exult there is great glory, but when the wicked rise up, men will be sought." The explanation [of this] is that the righteous will exalt and honor people about all the good traits that are found with them; but the wicked seek peoples' blemishes and their mistakes, to put them down - even when they have already left these actions and returned in repentance. Afterwards he said (Proverbs 28:13), "He who covers up his faults will not succeed; but he who confesses and gives them up will find mercy." For even though a penitent should not reveal his iniquities to people - as is to be understood from that which is stated, "but when the wicked rise up, men will be sought" - he is obligated to confess them [privately], like the matter that is stated (Psalms 32:5), "Then I acknowledged my sin to You; I did not cover up my guilt." And it is [also] stated (Jeremiah 2:35), "Lo, I will bring you to judgment for saying, 'I have not sinned.'" But the Sages of Israel, may their memory blessed, explained (Yoma 86b) [that] there are times when he who covers up his faults will not succeed - like with sins between a man and his fellow. As he does not attain atonement until he returns what was stolen, extorted or taken unjustly; and until he asks to be pardoned for that which he annoyed him, embarrassed him or spoke evil speech about him. [Likewise must he not cover up his] sins between a man and the Omnipresent that have become known to people. For one who sins publicly desecrates [God's] name (but Rashi, may his memory be blessed, in the Chapter [entitled] Yom HaKippurim, understands it in a different way. See there.) So he is obligated to grieve and mourn about it in front of people to sanctify [God's] name. And this is [the meaning of] that which is written (Jeremiah 31:19), "Now that I have turned back, I am filled with remorse; now that I am made aware, I strike my thigh." The meaning of, "I am filled with remorse," is regret and pain. For the essence of repentance is bitterness of the heart, as we have explained. And [the meaning of,] "now that I am made aware, I strike my thigh," is after people have been made aware and my iniquities have been publicized, I mourned with actions that were visible to people. [This is] like (Ezekiel 21:17), "strike the thigh"; and it is [also] stated (Job 33:27), "He declares to men, 'I have sinned; I have perverted what was right.'"
