Quotation על בראשית 49:22

And King Solomon, peace be upon him, said (Proverbs 14:9-10), “Fools will advocate guilt; among the upright, good will. The heart knows its own bitterness, and no outsider can share in its joy.” Its explanation is - the fool advocates guilt, since he searches for the blemishes of people and their guilt. So he will attribute defects to them and never speak about their praise or about something good that is found with them. And the analogy for this is that flies always all land on dirty places. And his saying, “fools will advocate (literally, fools advocates),” in the singular is [to address] each and every one of the fools, like (in Genesis 49:22), “(literally) daughters treads on the wall.” And our Rabbis said (Kiddushin 70a), “Anyone who is of flawed lineage never speaks in praise of [others]. And [his way is to] disqualify them with his own flaw.” “Among the upright, good will” - for it is the way of the just to cover over transgressions, and to praise a man when a good thing is found with him. And they spoke in ethics about a [simple] man and a sage who were walking past a carcass. The [former] said, “That carcass is so rotten!” The sage said, “How white are its teeth!” And [Solomon] said after this, “The heart knows its own bitterness.” And every sage knows that Solomon did not bring words that are not useful among his chosen teachings (Proverbs). Rather the matter is coming with regard to the first verse - to say that the evil of the fool that advocates guilt is because it is probable that the sinner has repented from his way. And no one knows the bitterness of the soul of a person, and its joy, besides him. And that lifts up the sin, for the essentials of repentance are according to the bitterness of his soul. Therefore the fool that mentions his iniquity sins and is guilty.
