We focus here on a single verse in chapter 25, and from it in particular we can learn a major principle in study. We have already seen that when a verse is complex and its literal meaning is not easily understood, one must immediately be prepared to find many explanations for it. When Scripture indicates something straightforward, it is stated explicitly; but when matters are not entirely clear, a wide field opens for various interpretations. Here, from the very first word, ma'adeh (מַעֲדֶה), there are two distinct approaches to its meaning, two different definitions - and yet, as we will see, there are even more than two interpretations.
מַעֲדֶה־בֶּגֶד בְּיוֹם קָרָה חֹמֶץ עַל־נָתֶר וְשָׁר בַּשִּׁרִים עַל לֶב־רָע׃ (כ) - Removing a garment on a cold day, like vinegar on natron, so is one who sings songs to a heavy heart.
Rashi explains that ma'adeh denotes removal, like vayasar, "and he removed," or vaya'adeh - a term of taking off, rather than an expression of adornment (adi) or decoration. According to this, ma'adeh beged refers to removing a garment, or a worn-out garment ready to be discarded. Here is a person taking off his clothes on a cold day - precisely the time when one needs to put on clothes rather than remove them.
Similarly, "vinegar on natron" (chometz al nater): nater (natron) is a type of soft earth or mineral from which vessels are formed, and when vinegar falls upon that earth - upon the vessel crafted from it - it dissolves it. In fact, natron is a cleaning agent, and when someone applies natron and then pours vinegar over it, the vinegar degrades the natron, counteracting and ruining it.
The Vilna Gaon explains: "Singing songs to a heavy heart" refers to someone who is troubled and grieving, and others sing to him. A person is feeling down and bitter, and his friend comes over: "Let me cheer you up; let me sing you a song." Is he in any mood to listen to songs right now? He says, "Leave me alone, turn off the light, just let me sit here in quiet." A "heavy heart" (lev ra) means that right now he feels distressed and bitter, and he is not looking for music. It does not uplift him or pull him out of his gloom. Just as stripping off one's garment on a cold day causes harm, and just as vinegar ruins natron, so one who sings songs to someone with a heavy heart not only fails to help him, but actively hurts him, deepening his heartache.
The Vilna Gaon asks: What do these three things hint at? He explains that they correspond to Torah, mitzvos, and character traits (midos). We saw earlier that midos are compared to garments - a person's character traits are, as it were, his clothing. One who possesses refined midos wears fine garments; one who lacks them has soiled or torn clothes.
When a person faces a temptation, when a negative trait flares up, and he does not break his negative impulses or master his inclination, this is "removing a garment on a cold day." The trial arrives, the cold sets in - this is the very moment to wrap oneself in virtuous traits - and instead, he strips off the garment. He discards his good midos and reacts harshly, acts vengefully, flies into anger, or even curses. The garment, which is noble character, is precisely what you cast aside on a freezing day.
"Vinegar on natron," says the Vilna Gaon, corresponds to mitzvos and transgressions. Natron is a cleansing agent for laundering, as Scripture states, "Though you wash with natron" (Yirmeyahu 2:22), which our Sages expound as referring to teshuvah (repentance). A person who washes with natron is engaging in teshuvah. And what does he do afterward? He pours vinegar onto the natron. In the very place where natron was applied and cleaned the stain, he goes and pours vinegar, neutralizing and destroying the natron. Why? Because teshuvah is a tool, an instrument of rectification; but if someone says, "I will sin and repent, I will sin and repent" - thinking, "Don't worry, there is always more natron" - he degrades the natron itself. The natron no longer works, and he is not granted the opportunity to achieve teshuvah.
"And singing songs to a heavy heart" corresponds to Torah. As our Sages expounded, this refers to someone who teaches Torah to an unworthy student with a corrupt heart, for through this he ends up doing more evil, in the spirit of the verse, "and transgressors will stumble in them."
And what does the verse come to teach? The Vilna Gaon explains: this connects directly to what we saw earlier - "trust in a treacherous man on a day of trouble." Do not rely on the yetzer hara, do not think that he is already fully conquered under your hand, for he will betray you on the day of distress. Realize that the moment a trial arrives, you will suddenly find "one who sheds a garment on a cold day" - you cast off your good character traits precisely when you needed to act with virtuous conduct. Suddenly you pour "vinegar upon natron" - after you have already repented, the yetzer awakens and makes you sin once again. And "singing songs to a heavy heart" - into the Torah you have studied, he injects an evil heart and corrupt intent into your Torah engagement.
Thus, the yetzer you trusted suddenly reveals itself to be a traitor. And as the Chovos HaLevavos states: you slumber while he remains awake and vigilant against you. You thought he was subdued under your hand, but suddenly he raises his head; suddenly you see that he stands tall and takes his position. You only imagined that you had overcome the yetzer hara; often it is only a temporary victory, after which he renews himself daily and gathers strength day after day.
The Ralbag understands the word ma'adeh not as Rashi and the Vilna Gaon did, explaining it as removal, but rather as related to ady, an adornment or ornament. A person who is cold puts on a garment, and there are two benefits to this: first, the garment shields him from the cold; and second, the garment is an ornament, it is beautiful, serving as an adornment that beautifies him.
The same applies to the continuation, and notice that the Ralbag inverts the perspective: one who applies vinegar to a stained garment after already treating it with natron (which removed the stain) - the vinegar completes the cleansing, imparting a fresh scent that eliminates mustiness. According to the first two explanations, vinegar upon natron is destructive and harmful, but according to the Ralbag it is the exact opposite - the entire verse speaks in a positive light.
And so it is with the third clause: "and singing songs to a heavy heart." The Ralbag explains that often when someone is disheartened, songs can lift him out of depression and the gloomy state he was in. It seems both approaches are true, depending on the personality or the type of gloom: there are people who specifically want to hear music when depressed, and it gradually frees them. Following this approach: just as clothing is beneficial in the cold, and vinegar is beneficial after cleaning with natron, so too it is positive to sing songs to someone with a sorrowful heart to draw him out of his depression.
The Metzudas David also follows the Ralbag's direction that ma'adeh beged means donning and draping an ornate garment upon oneself - yet he interprets it in a negative sense. A person feels cold, yet he wears a garment that provides no warmth simply because it is fashionable and ornate. This is very common: warm clothing might not be stylish, so people are willing to endure the cold in a garment that offers no warmth just because it looks finer. What good is the adornment? You are dressed up, but you are still freezing.
And this is comparable to one who pours vinegar upon natron, where due to the softness of the natron and the harsh acidity of the vinegar, the vessel is ruined and cracks form within it. So too with one who sings joyous songs to a broken heart: even if you see that the brokenhearted person listens and you see him smile - do not be misled. It is like vinegar upon the vessel: it creates cracks you cannot see, and ultimately the vessel will shatter. Even if you saw that he smiled and appeared pleased, realize that this does not lift him from his depression. Outwardly you may have managed to make him laugh, like someone telling a joke to a sick person: he laughed for a minute, but did that truly heal him? He promptly returns to his gloom. The grief remains buried deep in his heart, and you have accomplished nothing. It is just like an ornamental garment on a cold day: it looks attractive on the outside, but fundamentally it is inappropriate and inadequate - nothing more than mere decoration.
The Malbim also follows the approach that beged here relates to adornment (adi). He explains: although the garment is worn for beauty, on a cold day not only is there no beauty in it, but it also fails to warm the body, and the person freezes from the cold. At such a time, one must wear warm clothing, and whoever wears an ornamental garment - a garment that is merely decorative, as explained by the Metzudos - remains cold. So too is one who sings songs to a person steeped in sadness: not only does he fail to brighten his mood, but he actually adds to his sorrow. And it is like one who pours vinegar onto a vessel of natron, where the vinegar damages the vessel.
This is an allegory, says the Malbim, for anything directed toward an object that is not prepared to receive it. In simple terms: when you wish to take an action regarding a specific matter, ensure that it is suitable. Just as you would not pour water into an engine instead of oil, understanding that it is unsuitable - so too, an action should only be directed toward something prepared to receive it. Do not act upon someone who is not ready to receive it.
An example of this is a person trying to appease his fellow in the heat of his anger. His fellow is fuming, shouting, and cursing - and he comes along and tells him: "Calm down, calm down." Does that calm him? On the contrary, it only agitates him further; he shoves you away, becomes even more furious, and might even consider hitting you. One must ensure that the action being taken will be received properly. If not, it is like vinegar upon natron, or an ornamental garment on a cold day, or songs to a heavy heart. You have taken an action that was not properly received by the listener.
From here, the Malbim notes, one can understand the exposition of Chazal who applied this verse to one who teaches Torah to an unworthy student. What are you accomplishing? External beauty. And this external beauty is like a fine garment on a cold day - it provides nothing. You must ensure that the teachings penetrate within and have a genuine impact. If they do not affect him internally, it is nothing more than superficial beauty, and ultimately you will see that in a short time everything you taught him will vanish and be lost.
One verse, Ma'adeh beged beyom karah, and a wealth of interpretations: According to Rashi and the Vilna Gaon, ma'adeh means removal, and all three metaphors describe harmful things. The Gaon sees in them an allusion to character traits (middot), mitzvos, and Torah, as a continuation of Mivtach boged beyom tzarah ("a treacherous trust on a day of distress") - do not trust the Yetzer Hara, for precisely in the moment of trial he strips away the garment of character traits, weakens the natron of repentance, and injects a heavy heart into the study of Torah. The Ralbag interprets ma'adeh as adornment in a positive light: the song lifts the sad person out of his depression. Metzudas David and the Malbim, however, interpret adornment in a negative light: a decorative garment does not warm, vinegar cracks the natron vessel, and singing to an aching heart only increases sorrow. From this emerges the Malbim's overarching principle: do not direct an action toward something that is not prepared to receive it - neither appeasing a friend in the heat of his anger, nor settling for external beauty where internal transformation is required.
