Chapter 18 of Mishlei opens with a single verse that encapsulates the entire concept of bodily desire: what desire does to a person, how it separates him from the community, and how it strips away his sense of shame. We will examine it in depth: Rashi's commentary, the midrashic teaching of Chazal regarding Lot, the explanations of Rabbeinu Yonah, and the insights of the Vilna Gaon.
לְתַאֲוָה יְבַקֵּשׁ נִפְרָד בְּכׇל־תּוּשִׁיָּה יִתְגַּלָּע׃ (א) - One who pursues desire seeks separation; in all sound wisdom his shame is exposed. (1)
Rashi explains: "He who separates" refers to one who separates himself from the Holy One, Blessed be He, meaning he no longer observes the mitzvot, driven by his heart's desires and his evil inclination. Such a person - "in all tushiyah he is exposed [yitgala]." "Yitgala" means to be revealed: his lowliness, his disgrace, and his shame will become apparent. And according to Rashi, "tushiyah" refers to the Torah, which is called tushiyah because it weakens (mateshet) a person's physical strength; the meaning is that his disgrace will be revealed among Torah scholars.
The meaning is simple: when a person lives connected to Torah scholars and subsequently separates from them and declines spiritually, when he returns to the company of Torah learners, it immediately becomes apparent how much of an am ha'aretz (unlearned person) he has become, how much Torah he has forgotten, and how his pursuit of desire brought him to a state where he no longer commands what he once mastered when he was among them. Thus, "in all tushiyah he is exposed" - his disgrace is revealed among the masters of Torah wisdom.
Chazal expound this verse, as cited by Rashi, in reference to Lot, who separated from Avraham: "And Lot chose for himself the entire plain (kikar) of the Jordan." The Gemara expounds the entire verse as alluding to immorality: "For on account of a harlot, a man is brought to a loaf (kikar) of bread." Lot chose Sedom specifically because of their wicked deeds; that was what attracted him. Some have noted wittily: Why did Lot become drunk and uncovered in his tent? Because he saw the plain of the Jordan, "that it was well-watered (mashkeh) everywhere" - he saw a drink (mashkeh), and headed straight in that direction. In short: Lot chased after his desires.
And what was his end? "In all tushiyah he is exposed" - his disgrace was exposed in synagogues and study halls, in two ways. First, every single year we publicly read the shameful account of Lot and his daughters. Second, "An Ammonite and a Moabite shall not enter the congregation of Hashem" - it was decreed that his descendants who came from his daughters may never enter the congregation of Hashem. It turns out that one who pursues desire will be exposed in all tushiyah: his disgrace and lowliness are exposed and publicized for all to see.
Rabbeinu Yonah explains that this verse comes to censure physical desire: a person who pursues the desires of his heart becomes separated from every friend. This observation is remarkably true: my desires and your desires are not the same. When I crave one thing, you crave something else, and I am unwilling to surrender what I want for the sake of what you want. Therefore, when there is a group of people and each is driven by his own desires - "he seeks separation": he seeks to break away, because his desires do not align with those of others, and he is unwilling to set aside his desire for his fellow's. In this way, he alienates himself from all his friends.
Where do we see this with our own eyes? A group of people is sitting together, and suddenly you notice one of them wandering outside. What is he doing out there? He felt the urge to smoke. There you have it: "He who pursues desire seeks separation" - he separated from everyone because he had a physical urge he needed to fulfill.
The verse teaches an additional point about one driven by desire: not only does he alienate himself from his peers as a result of his lust, but he feels no shame even when it brings him to utter disgrace. Desire blinds his eyes from seeing its inherent flaw and ugliness.
Consider an example: a respectably dressed person walks past a dumpster and suddenly spots something that might be of use to him. How much is it worth? Twenty shekels, thirty shekels - just buy it! But no, it would be a shame to leave it; someone threw it out for nothing. What does he do? He looks for a way to climb into the dumpster to pull it out. Now imagine an acquaintance passes by and sees him - what embarrassment, what disgrace! "What are you, homeless? Why are you rummaging through dumpsters?" Yet he cannot resist his craving. Because he is gripped by a lust for money and saw something that piqued his interest, he is willing to bring himself to total disgrace. This is the meaning of "against all sound wisdom he rages (yitgala)" - his disgrace will be revealed in the eyes of the wise who witness his conduct.
Rabbeinu Yonah offers an additional explanation: "yitgala" means that he expresses his cravings with his lips. There is one who harbors a desire but at least conceals it, while another does not conceal it but reveals it to others, and through such speech he degrades himself and brings great shame upon himself. A person might say, "Look at that fellow, how I feel like hitting him right now!" You say this to express your heart's impulse, but the listener thinks: what a vile person, how could he even contemplate such a thing, raising a hand against someone? Instantly, your worth drops in his eyes. A lustful person feels no shame even before the wise: he is willing to speak of all his personal trivialities and vanities that portray him in a negative light, and because of his relentless pursuit of desire, he is oblivious to the disgrace.
At an engagement celebration, it is customary for the host to give charity to the needy who come to collect. Yet on one occasion, the father of the chassan was seen approaching the father of the kallah and boasting: "Did you see that fellow who came here collecting charity? Did you see how I brushed him off? I told him I only have a hundred or two-hundred bill, and that was that." At the very least, be ashamed! If you do not want to give, do not give; if you believe he is dishonest, do not give. But why come and brag about it, recounting how you humiliated a person asking for charity? "Against all sound wisdom he rages" - even before the wise, his stinginess is exposed, along with his corrupt nature and character traits. This is a person who pursues his desire without restraint, about whom it is said, "he knows no shame," and "for the wicked boasts of his soul's desire" - the wicked person actually prides himself on his base desires and the improper things he has done.
In another setting among non-observant people, each one sat and boasted of the clever tricks and scams he had pulled on others. It was truly shocking. One fellow recounted how he sold a bus tour at more than double the competitor's price, explaining to the customer that his bus had orthopedic seats and air conditioning. When the customer complained that the air conditioning was never turned on, he replied, "I said the bus has air conditioning; I never said I would run it - turning on the air conditioning is an extra two hundred shekels." He sits and relates without any shame how he cheated people! What are you telling everyone? That you are a thief? But a person driven by lust no longer feels shame - "the wicked boasts of his soul's desire." He even views it as a badge of honor: look how clever I am, how shrewd. This is utterly flawed and corrupt. "Against all sound wisdom he rages" - he is ready to expose his disgrace even among a large crowd and before wise men, without a shred of shame.
Rabbeinu Yonah adds an explanation that must be understood from the context. As a preliminary note, the familiar division of chapters was not established by the author of the book, but is a later division from several centuries ago of non-Jewish origin. The authentic Jewish division is into parashiyos - open (petuchah) and closed (setumah) - not chapters. It is therefore not surprising if we interpret this verse by linking it to the end of the preceding chapter; it is not a disconnected chapter, but simply one verse following another.
The preceding verses dealt with the subject of speech: "Even a fool who keeps silent is considered wise," and "One who restrains his words possesses knowledge; a man of understanding is of a calm spirit." Rabbeinu Yonah explains that our verse also deals with speech: one who craves his desires has no restraint over his spirit, speaking whatever his heart desires, and through this "he seeks separation." If you know how to muzzle your mouth, you know to tell yourself: here I should not speak, here I should not say this. But if you do not do so, no one will be able to tolerate you, because you have an itchy trigger finger on your tongue. Whatever crosses your mind, you blurt out immediately - even if it mocks someone, dismisses his words, or casts him in an unfavorable light.
Such people are truly pitiable: whatever enters their heart spills out; they have no ability to remain silent and restrain their words. Whatever is on their mind is blurted out immediately without pause. Such a person is exceedingly low, and he is a slave to desire. One person's craving is for money, while another's craving is for speech - he is incapable of keeping quiet. There is a popular expression today: "He talks endlessly." He talks and talks, always needing to say something; and when he has nothing to say, he speaks about that, mocks you, disparages this, or derides a word you uttered. This is the desire we spoke of in "Even a fool who keeps silent is considered wise" - the craving for speech.
And what is its consequence? "He who separates will seek" - this person will have no friends or loved ones; everyone will separate from him. Who can stand near you? Who can endure constant words of disparagement, jest, and mockery? Furthermore, "for he will sin and become guilty through his words to his friends" - this leads to sin and one will inevitably stumble, as "whoever multiplies words brings about sin" and "in a multitude of words transgression does not cease." In a torrent of words, you are bound to hurt someone and say something disparaging. And even if you claim that you are not hurting anyone - "for the multitude of his words will become a burden." Is it pleasant for someone to stop you and say: "Could you give us a few minutes of quiet? You have been speaking non-stop for an hour and a half"? People say: Do not invite him, last time he talked our heads off. A person who does not control his lust for talk, even if he does not insult everyone - the very fact that he never stops talking makes people avoid his company.
Rabbeinu Yonah adds further: "He quarrels with all sound wisdom" - in every matter of wisdom, he reveals and expresses his opinion, even though he has never studied wisdom, "for such is the character of those who crave to speak and reply." How true this is. There is the kind of person who knows everything: ask him what he has studied, what his background is - yet whatever you ask, he knows it all. There is an insightful observation: if you meet a person who reveals everything he knows in five minutes, realize that this is truly all he knows. He emptied out everything in five minutes, and that is all there is.
It is precisely the wise who do not comment on everything and do not feel compelled to constantly voice an opinion. Particularly on a subject in which they are not well versed, they will say: In this matter, I prefer not to comment. But the boor and the fool, who feel an incessant urge to air their views, talk about every subject without the slightest clue. He once heard some vague rumor, and immediately he understands, immediately he has what to say, offering an opinion, taking a side, and arguing. These are people who crave speech: "In all sound wisdom" - even in wisdom of which he has no understanding whatsoever - "he quarrels," exposing his opinion in every area.
The Vilna Gaon explains the verse as if it were ordered: "One who separates seeks desire." When someone separates from the Torah, what is the first thing he seeks? Desire. And how true this is. One sees, Heaven forbid, the phenomenon of dropouts, those who could not hold on; what is the first thing they go and do? Pursue physical desires. Supposedly, having left the yeshivah, one should go and look for another framework, find a job, plan the road ahead. The issue here is not whether the decision itself was right or wrong; suppose he decided that yeshivah is not suitable for him, let him go and look for something else. But no: the first thing he seeks is indulgence. Until now there was a mashgiach, there was a rosh yeshivah, he felt constrained; now that he is no longer in yeshivah, he feels free to cast off all restraint.
A former member of the "Hillel" organization once recounted his story. The name "Hillel" ironically evokes the verse, "For the wicked boasts of his soul's desire." This organization was established to aid individuals who wish to abandon religious observance, helping them acclimate to secular society. That individual, who ultimately returned to observant life, recounted: After leaving the yeshivah, the first thing I wanted was to consume the world. Until then, this was forbidden and that was forbidden - and now, everything was open. Indeed, there was everything: television, videos, internet, pleasures at will. But a stage arrives when you realize that this is not truly living. You felt like a starving person who was served food - fine, but what now? And then you suddenly realize that no one is truly standing behind you. What do they do for you? They take you out, helping you indulge your desires. But what now? Who helps me from here on? And suddenly you discover that you are all alone. This is "one who separates seeks desire."
One can go even further. If one were to analyze by percentages the reasons why a person abandons Torah study and the observance of the mitzvot, the answer is desire. In the past, there was still some barrier of shame, and a person felt compelled to cloak his departure in the guise of seeking knowledge, science, broadening horizons, or higher education, so long as he would not be perceived as weak-willed and unable to resist his passions. Today, people say it openly: "I felt too restricted; here I feel much freer." The barrier of shame has been removed. All the external excuses offered - "the mashgiach did not understand me," "the rosh yeshivah looked down on me" - are merely a pretext, a fig leaf to justify his actions. What lies behind it all? Physical desire.
This is also the primary reason why a person hesitates to return in teshuvah: desire. When a person contemplates teshuvah, the foremost deliberation is not whether Torah is true, whether it is binding, or whether Heaven and Gehennom exist. One should know that the intellectual conviction is the easiest and most straightforward part; one can become convinced that there is a Creator in a single lecture, and demonstrating that the Torah is true is relatively simple. The difficult part is crossing the psychological barrier: starting tomorrow, one cannot simply wake up in the morning, drink coffee, eat cake, and head out to work; starting tomorrow, one must put on tefillin, and at the end of the week there is Shabbat. What must be given up? Waking up earlier, dedicating time to prayer, giving up the game on Shabbat, the weekend trip with friends. Ask any baal teshuvah who faced this dilemma: the primary consideration was a calculation of profit and loss - what will change in my life, and which desires will I have to renounce? How does one transform from a person who pursued physical pleasures into one who pursues intellectual and spiritual truths? That is the difficult and complex part.
This is the meaning of "one who separates seeks desire": Who separates from the Torah? One who seeks desire. Who fails to connect to the Torah? One who seeks desire. And whoever is willing to sacrifice his physical desires on the altar of Torah and holiness is the person who will truly engage with Torah and connect to it.
Furthermore, when a person abandons the Torah, he leaves behind one of the greatest shields he has against desire. The Rambam points out that concerning the Torah it is said, "be ravished always with her love" - if a person is absorbed in the love of Torah, he is bound to holiness; and if not, he will inevitably become absorbed in the love of other things. Likewise, the Rambam states that thoughts of immorality are found only in a heart devoid of wisdom. If you fill the heart with wisdom, immorality and all else depart from a person; but if you have not filled it with wisdom, snakes and scorpions make their dwelling there. This is what the Vilna Gaon explains in Divrei Shlomo: one who separates from the Torah has abandoned the greatest defense against those snakes and scorpions, and therefore, the moment he separates, he is immediately drawn after his desires, with no shield or buckler to protect him.
Regarding "his shame is exposed in all wisdom" (bechol tushiyah yitgala), the Vilna Gaon explains: his disgrace is revealed everywhere. The Gemara in Pesachim speaks very severely of a talmid chacham who frequents feasts everywhere, calling him a "bar melachech pinkei" - a dish-licker. This refers to a scholar who shows no respect for the Torah within him: whenever an opportunity arises and he is invited - there is a feast, he comes; there is food, he shows up. People observe him making sure not to miss any of the three courses, and if it is possible to get an extra portion from the waiter, even a third and a fourth; and from the desserts, too, he takes care to sample every single kind, taking generously so there will be no halachic doubt whether he ate enough for Birkat HaMazon, and even citing the prohibition of wasting food (bal tashchit), since it will be thrown out in the end anyway. How do people talk about him? "Did you see that rabbi? At every wedding he arrives at the start and stays until the end; it seems he came only to eat." What shame, what disgrace, and what a desecration of the Torah - and the Gemara speaks of such a person in the harshest terms.
This is "his shame is exposed in all wisdom": because he abandoned the Torah, he clung to desires, and because he clung to desires, his disgrace is exposed in all wisdom - his lust is laid bare before the wise and before the great crowd observing his actions. Yet as noted, he himself does not even realize it: because he is consumed by pursuing his desires, he is oblivious to what is happening around him and is blind to his own disgrace.
One verse, with several distinct facets. According to Rashi: one who separates from the Holy One, blessed be He, in pursuit of his desire - his disgrace is exposed among Torah scholars, and Lot stands as the eternal archetype of this. According to Rabbeinu Yonah: the person consumed by desire separates from his companions because he is unwilling to relinquish his cravings, feels no shame in disgracing himself, and even articulates his lusts openly; while the one consumed by the desire to speak, who cannot restrain his words and voices an opinion on every subject he knows nothing about, drives everyone to separate from him. And according to the Vilna Gaon: "One who separates seeks desire" - one who separates from the Torah seeks desire first and foremost, for he has cast off the greatest defense against the serpents of the evil inclination. From here emerges the practical conclusion: lust is the true underlying reason for abandoning the Torah and the greatest obstacle on the road to teshuvah, and one who is prepared to sacrifice his desires upon the altar of Torah - he is the one who will truly merit to cling to it.
