Humans are the apex predator on Earth. We possess superior intelligence, which we communicate through speech in order to cooperate with other humans, giving us a considerable advantage in forming groups, as we can pool workloads and specializations. Speech is the tool through which we actualize our intelligence and self-awareness.

Through speech, we have formed societies and built civilizations; developed science and medicine; literature and philosophy. Crucially, we do not have to learn everything from personal experience, because we can use language to learn from the experience of others.

The Torah holds language and speech in the highest esteem because words are tangible. Indeed, they are the fabric of Creation – וַיֹּאמֶר אֱלֹהִים, יְהִי אוֹר; וַיְהִי-אוֹר.

R’ Jonathan Sacks notes that the concept of covenant is a performative utterance that creates a relationship between two people – a mutual commitment created through speech. Whether it’s God giving us the Torah, or a husband marrying his wife; relationships are fundamental to Judaism. We can only build relationships and civilizations once we can make commitments to each other.

We make important decisions based on thoughts and feelings based on words on a page or a conversation with someone. It has been said that with one glance at a book, you can hear the voice of another person – perhaps someone dead for thousands of years – speaking across the millennia clearly and directly to you.

Given the potency of speech and language, the Torah emphasizes in multiple places: the laws of the metzora; the incident where Miriam and Ahron challenged Moshe; and even the Torah’s choice of words about the animals that boarded the Ark:

מִכֹּל הַבְּהֵמָה הַטְּהוֹרָה, תִּקַּח-לְךָ שִׁבְעָה שִׁבְעָה–אִישׁ וְאִשְׁתּוֹ; וּמִן-הַבְּהֵמָה אֲשֶׁר לֹא טְהֹרָה הִוא, שְׁנַיִם-אִישׁ וְאִשְׁתּוֹ – Of every clean creature, take seven and seven, each with his mate; and of the creatures that are not clean two, each with his mate. (7:2)

The Gemara notes that instead of using the more concise and accurate expression of “impure,” the Torah uses extra ink to express itself more positively – “that are not clean” – אֲשֶׁר לֹא טְהֹרָה הִוא. The Lubavitcher Rebbe preferred to refer to “death” as “the opposite of life”; and hospital “infirmaries” as a “place of healing.”

The Torah cautions us of the power of speech repeatedly in more general settings:

לֹא-תֵלֵךְ רָכִיל בְּעַמֶּיךָ, לֹא תַעֲמֹד עַל-דַּם רֵעֶךָ:  אֲנִי, ה – Do not allow a gossiper to mingle among the people; do not stand idly by the blood of your neighbor: I am Hashem. (19:16)

The Torah instructs us broadly not to hurt, humiliate, deceive, or cause another person any sort of emotional distress:

וְלֹא תוֹנוּ אִישׁ אֶת-עֲמִיתוֹ, וְיָרֵאתָ מֵאֱלֹהֶיךָ: כִּי אֲנִי ה, אֱלֹהֵיכֶם – Do not wrong one another; instead, you should fear your God; for I am Hashem. (25:27)

It’s interesting that both these laws end with “I am Hashem” – evoking the concept of emulating what God does; which suggests that just as God speaks constructively, so must we – אֲנִי ה.

The Gemara teaches that verbal abuse is worse than financial damages because finances can be restituted but words can’t be taken back.

The Lubavitcher Rebbe taught that as much as God creates with words, so do humans.

Of course, one major caveat on harmful speech is the intent. If sharing negative information has a constructive and beneficial purpose that may prevent harm or injustice, there is no prohibition, and there might even be an obligation to protect your neighbor by conveying the information – לֹא תַעֲמֹד עַל-דַּם רֵעֶךָ.

Language distinguishes humans from other animals. It’s what makes us human. God creates and destroys with words, and so do we.

Rather than hurt and humiliate, let’s use our powerful words to help and heal; because words and ideas can change the world.

One of the daily features of the Mishkan service was the service of preparing and lighting the Menora. The Torah highlights that Ahron took the ceremony deeply seriously:

דַּבֵּר, אֶל-אַהֲרֹן, וְאָמַרְתָּ, אֵלָיו: בְּהַעֲלֹתְךָ, אֶת-הַנֵּרֹת, אֶל-מוּל פְּנֵי הַמְּנוֹרָה, יָאִירוּ שִׁבְעַת הַנֵּרוֹת. וַיַּעַשׂ כֵּן, אַהֲרֹן–אֶל-מוּל פְּנֵי הַמְּנוֹרָה, הֶעֱלָה נֵרֹתֶיהָ: כַּאֲשֶׁר צִוָּה ה, אֶת-מֹשֶׁה – Speak to Ahron, and say to him; “When you rise to light the Menora, light seven candles.” Ahron did so; he lit the candles on the Menora, just as Hashem had commanded Moshe. (8:2-3)

But if you think about it for a minute, it’s a little odd to say that Ahron followed his instructions – וַיַּעַשׂ כֵּן / כַּאֲשֶׁר צִוָּה ה. What is so noteworthy about doing what he was supposed to do – how else would he light the Menora?

Picking up on this strange remark, Rashi quotes the Sifri that Ahron performed his duties scrupulously, precisely the way he was told for the rest of his life, and never changed or deviated in any way.

R’ Simcha Bunim of Peshischa notes that as much as the comment is about Ahron not changing how he performed his duties, it’s equally a comment about how his duties didn’t change him. Some people let privilege and honor get to their heads – but not Ahron.

The Sfas Emes notes that lighting the Menora wasn’t a particularly prestigious ceremony, in that any Kohen could kindle the lights; but Ahron took it seriously enough that he insisted on doing it himself every day for the rest of his life.

Mastery is typically boring. Finishing your fiftieth marathon is probably less special than your first.

It’s normal.

The Ishbitza notes that the highest praise for Ahron is that he retained that initial desire, and it never got stale or boring for him. He kept challenging himself to find something new and exciting, so he lit the Menora his last time with the same enthusiasm as the first.

The more we experience something, the more our enthusiasm and attention typically wane. Predictability and comfort put an end to fresh euphoria; when we know what to expect, our excitement wears off and boredom sets in. That’s why we need to keep things fresh if we’re focused on a long term project or goal.

It’s something often seen with young professional athletes who lose their way – they think they’ve made it, and stop putting in the work that would take them to the elite tier; and the older pros all comment that the youngsters have lost their concentration and focus.

The highest form of mastery is in valuing each repetition and finding the novelty and excitement in it.

By being fully present in each moment, and devoting your undivided attention, things won’t get boring.
