When Ahron was instructed to light the Menora, we find that the Torah emphasizes something seemingly out of place:
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 יְהוָה, אֶת-מֹשֶׁה – Speak to Ahron, and say to him; “When you rise to kindle the lights on the Menora, light seven,”. And Ahron did so; he lit the candles on the Menora, just as Hashem had commanded Moshe. (8:2-3)
Rashi notes that וַיַּעַשׂ כֵּן – that the person commanded did as directed, is not regularly found in the Torah; it is assumed that when God speaks to you, you do as told.Rashi explains that it appears here to praise Ahron.
The Sfas Emes takes the praise to mean that Ahron was meticulous to light the Menora every day himself, when in fact, it could have been done by any member of his family. That is to say, he retained the initial enthusiasm for the job his entire life – וַיַּעַשׂ כֵּן as though that were the day he was instructed. Later, we find this lesson lost:
וַיִּסְעוּ מֵהַר ה’ דֶּרֶךְ שְׁלֹשֶׁת יָמִים – They travelled from the mountain of God a three-day journey. (10:33)
The Gemara in Shabbos teaches that this alludes to the Jews straying from their closeness to Hashem. They literally left where God was.
Rashi notes that it was their departure from Sinai that cultivated their craving for meat – the manna was not enough. The Ramban compares their attitude to leaving Sinai to a child running out of school. They left Sinai – the place where they were exposed to God and the Torah – in excitement that the “class” was over. The Chasam Sofer explains that had they not thrown off the yolk of Torah and fled like a child running from school, they never would have developed their infamous craving for meat.
The Mishna in Avos says: “Whoever throws off the yoke of Torah, they place the yoke of drech eretz upon him,”. There is a fixed amount of input that must be channeled one way or another. Derech eretz here refers to physical desires. This catalyzed an unfortunate chain of events. The Jews were supposed to go straight from receiving the Torah into Eretz Yisrael. Yet, because of the attitude with which they left Mount Sinai, they developed their craving for meat. Because of their craving for meat, they were delayed for 30 days while many were lost to plague. This delay allowed the opportunity for Miriam to slander Moshe, causing a further delay of seven days while waiting for her purification. The episode of the spies followed, deduced from the juxtaposition of the episodes of Miriam next to the episode of the spies; due to which the fate of that generation was sealed. They were to die out over the course of the next 40 years, never to reach Eretz Yisrael.
It was during that time that Moshe Rabbeinu himself was denied the opportunity to enter Eretz Yisrael because of the incident wherein he struck the rock. Had Moshe Rabbeinu entered Eretz Yisrael, there never would have been a destruction of the Holy Temple, and the ensuing exile. History would have been drastically different. What emerges is that Judaism is not exclusively about learning Torah and doing mitzvos, regardless of one’s intentions and attitude. Chovos halevavos, duties of the heart and spirit, are critical. It is because of poor attitude to how we relate to Torah and mitzvos that we find ourselves in galus to this day.
