Days on the Jewish Calendar: Shevat
Rosh Chodesh Shevat: Part 1
Moshe Rabbeinu's explanation of the Torah in seventy languages, and the later command to inscribe it in seventy languages on the stones at the Yarden, is set against Chazal's account of the translation made for Talmai HaMelech, a day considered as terrible as the making of the Egel. After ruling out Greek itself as the special problem, since both of Moshe's translations included it, the analysis turns to what avodah zarah actually is: crediting the sun and other forces of nature with power of their own rather than recognizing them as mere tools in Hashem's hand. That definition explains why a literal translation risks suggesting a power alongside Hashem, and why only a translation done for the sake of Hashem's command, as Moshe's was, could never lead to such a mistake.
15 Shevat: Part 1
The Gemara in Taanit's sharp question, is a person really a tree of the field, is read as proof that the pasuk means more than a simple parable, since a mere comparison would not justify the minhag of celebrating the trees' own Rosh Hashanah. Understanding a person as an olam katan made up of domem, tzomeach, chai, and medaber, the tzomeach of the nefesh is identified as a person's middot, which is why even a person's highest faculty, his seichel, only earns the title adam when it produces real feeling and action, echoing the pasuk vahashevota el levavecha. A tree's other lesson, its constant rootedness in the ground that sustains it, is offered as a second model: that a Yid must stay constantly connected to Hashem, the source of his life.
Rosh Chodesh Shevat: Part 2
Since Lashon Kodesh is described as the very language Hashem speaks, the discussion asks how learning Torah in any other language could ever carry the din of divrei Torah, given that even Torah Sheba'al Peh takes its words seriously. The answer is that this status had to be established through Moshe Rabbeinu specifically, since every chiddush in Torah must pass through him, which is why he waited until his final day to accomplish it rather than acting on it earlier out of concern for the Erev Rav or a distant future golus. A further distinction is drawn between explaining the Torah verbally in other languages and commanding it be written in their letters at the Yarden, two separate accomplishments that together established the kedushah of Torah even in translation and even in writing.
15 Shevat: Part 2
Since every Yom Tov falling on the 15th of the month coincides with the moon's fullness and the completion it represents for the Yidden, Tu B'Shvat is shown to share that pattern with Pesach and Sukkot, yet a comparison to Tu B'Av suggests it carries an even greater maalah. The seeming contradiction between ilanot's renewal of the koach hatzomeach and the completeness of the 15th day is resolved by explaining that a Yid's true shleimus, tied to Hashem's own ein sof, is precisely the recognition that he must always keep growing higher. That growth is then located specifically in the realm of ta'anug and lifnim mishurat hadin, since Tu B'Shvat celebrates fruit rather than grain, the extras of Torah and mitzvot beyond what is strictly required.
Rosh Chodesh Shevat: Part 3
Chazal's statement that Moshe said Chumash Devarim 'mipi atzmo,' on his own, is reconciled with the principle that denying any single word of Torah is kefirah by explaining that Devarim alone passed through Moshe's own sechel before being written down, unlike the first four chumashim. That distinction is then used to explain why Nevi'im U'Ketuvim carry the status of divrei kabbalah and not only divrei nevuah, since Chumash Devarim serves as the yesod that first showed words shaped by a human seichel could still be Torah. The same chiddush is shown to be the source of Torah Sheba'al Peh itself, where a chacham's own reasoning becomes the vessel through which the ratzon and chochmah of Hashem are revealed.
15 Shevat: Part 3
Chamishah Asar B'Shevat falls on the full moon, a symbol of shleimut, yet its Yom Tov celebrates ongoing growth, teaching that true completeness means recognizing how much further one must climb. The gematria equating ilan with Shevat, and the month's dual associations with the tribes of Yosef (hosafah, constant addition) and Asher (pleasure that expands the bone), root this theme in the structure of the twelve months and the twelve tribes. A closing look at why the day's agricultural halachos apply only in Eretz Yisrael resolves into the teaching that every Jew is essentially a ben Eretz Yisrael, obligated to keep growing and to embrace practice lifnim mishurat hadin.
Month of Shevat
Every month of the year carries its own tziruf, letter-combination, of the four-letter Name of Hashem, and Shevat's is hei-yud-vav-hei, drawn from the pasuk hamer yemirenu vehaya hu in the halachos of temurah, where an animal wrongly exchanged for a korban becomes kadosh together with the one it replaced. Since each month also corresponds to one of the twelve shevatim according to birth order from Nissan, Shevat corresponds to Yosef, whose singular achievement, as Rashi notes, was ruling all of Mitzrayim while remaining the same tzaddik he was as a shepherd, bringing kedushah into thoroughly secular affairs rather than being pulled down by them. This is the deeper meaning of his name, Yosef Hashem li ben acher, transforming what is acher, other, into a ben, a son of Hashem, precisely the pattern of the temurah pasuk that names Shevat: turning what seems secular into something sacred without loss to the one who does the turning.
Shabbat Shirah
Shabbos Shira's account of the sea splitting opens into a close reading of the pasuk 'vayashav hayam le'eitano' and the midrashic condition Hashem made with the sea at creation. Working through the Rambam's Moreh Nevuchim, a difficulty the Tosafos Yom Tov raises, and the deeper halachic concept of a tenai, the analysis argues that Hashem built this condition into creation itself so that the world's existence would depend on it. The conclusion: the true metziut of the universe is Torah and Bnei Yisrael, giving even a physical, limited world a connection to the infinite.
Tu Beshvat
Starting from the halachic mechanics of Rosh Hashanah for the trees, including the Beis Shammai/Beis Hillel dispute over when the water's judgment takes effect and why the date matters for maaser, the class moves into the lessons a Yid draws from trees: roots as the mitzvos that keep Torah from blowing away, constant growth, and always bearing fruit. It closes with the gematria linking אילן to Shevat and to Hashem's names of infinity, and the Gemara's question of what it really means that a person is compared to a tree.
