Musar su Ezechiele 21:13

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.'"

And corresponding to this they said (Yalkut Shimoni Yechezkel 361): "'[So said the L-rd G-d:] I shall remove the turban and lift off the crown [the humble will be uplifted, and the high will be humbled]' (Yechezkel 21:31) - whoever is great in this world will be small in the World to Come". We also learn the opposite: if one is small in this world, his time of greatness will be in the World to Come.

The detriments of this trait are abundance and satiation in the good of this world, similar to what scripture states explicitly: "lest when you have eaten and become sated [and built good houses...] and your heart grows haughty..." (Devarim 8:12-14).
