עַל הַיִּיחוּד, וְעַל הַפְּנוּיָה. יִחוּד? דְּאוֹרָיְיתָא הוּא! דְּאָמַר רַבִּי יוֹחָנָן מִשּׁוּם רַבִּי שִׁמְעוֹן בֶּן יְהוֹצָדָק: רֶמֶז לְיִיחוּד מִן הַתּוֹרָה מִנַּיִין? שֶׁנֶּאֱמַר: ״כִּי יְסִיתְךָ אָחִיךָ בֶן אִמֶּךָ״. וְכִי בֶּן אֵם מֵסִית, בֶּן אָב אֵינוֹ מֵסִית? אֶלָּא לוֹמַר לָךְ: בֵּן מִתְיַיחֵד עִם אִמּוֹ, וְאֵין אַחֵר מִתְיַיחֵד עִם כׇּל עֲרָיוֹת שֶׁבַּתּוֹרָה. אֶלָּא אֵימָא: גָּזְרוּ עַל יִיחוּד דִּפְנוּיָה. ״וַאֲדֹנִיָּה בֶן חַגִּית מִתְנַשֵּׂא לֵאמֹר אֲנִי אֶמְלֹךְ״. אָמַר רַב יְהוּדָה אָמַר רַב: מְלַמֵּד שֶׁבִּיקֵּשׁ לְהוֹלְמוֹ, וְלֹא הוֹלַמְתּוֹ. ״וַיַּעַשׂ לוֹ רֶכֶב וּפָרָשִׁים וַחֲמִשִּׁים אִישׁ רָצִים לְפָנָיו״. מַאי רְבוּתָא? אָמַר רַב יְהוּדָה אָמַר רַב: כּוּלָּן נְטוּלֵי טְחוֹל וַחֲקוּקֵי כַּפּוֹת רַגְלַיִם הָיוּ. מַתְנִי׳ ״לֹא יַרְבֶּה לּוֹ סוּסִים״, אֶלָּא כְּדֵי מֶרְכַּבְתּוֹ. ״וְכֶסֶף וְזָהָב לֹא יַרְבֶּה לּוֹ מְאֹד״, אֶלָּא כְּדֵי לִיתֵּן אַפְסַנְיָא. וְכוֹתֵב לוֹ סֵפֶר תּוֹרָה לִשְׁמוֹ. יוֹצֵא לַמִּלְחָמָה – מוֹצִיאָהּ עִמּוֹ, נִכְנָס – הוּא מַכְנִיסָהּ עִמּוֹ, יוֹשֵׁב בַּדִּין – הִיא עִמּוֹ, מֵיסֵב – הִיא כְּנֶגְדּוֹ, שֶׁנֶּאֱמַר: ״וְהָיְתָה עִמּוֹ וְקָרָא בוֹ כׇּל יְמֵי חַיָּיו״. גְּמָ׳ תָּנוּ רַבָּנַן: ״לֹא יַרְבֶּה לוֹ סוּסִים״ – יָכוֹל אֲפִילּוּ כּ

English: about seclusion, that a man should not be secluded with women who are forbidden to him, and about a single woman. The Gemara objects: Seclusion with a woman forbidden by familial ties is prohibited by Torah law, and was not a rabbinic decree issued in the time of David. As Rabbi Yoḥanan says in the name of Rabbi Shimon ben Yehotzadak: From where is there an allusion to the halakha that seclusion is forbidden by Torah law? As it is stated: “If your brother, the son of your mother, entices you” (Deuteronomy 13:7). One can ask: But does the son of a mother entice, and does the son of a father not entice? Why mention only the son of a mother? Rather, this verse serves to tell you that only a son may be secluded with his mother. Sons are frequently with their mother, and two half-brothers of one mother consequently have the opportunity to grow close to one another. But another individual may not be secluded with those with whom relations are forbidden by the Torah, including a stepmother. Therefore, half-brothers of one father spend less time together. Since seclusion, then, is prohibited by Torah law, how did Rav say that it was prohibited by a decree issued in King David’s time? Rather, say that they decreed against seclusion of a man with a single woman, to prevent occurrences like that of Amnon and Tamar. Apropos Amnon, the Gemara cites traditions about another son of David: “Now Adonijah, son of Haggith, exalted himself, saying: I will be king” (I Kings 1:5). Rav Yehuda says that Rav says: The term “exalted himself” teaches that he sought for the monarchy to fit him, but it did not fit him. The verse continues: “And he prepared for himself chariots and riders and fifty people to run before him” (I Kings 1:5). The Gemara asks: What is the novelty of these actions, since other wealthy people do the same, even if they are not the sons of kings, with designs on the throne? Rav Yehuda says that Rav says: What was unique was that the runners all had their spleens removed and had the soles of their feet hollowed, removing the flesh of their feet, and these two procedures enhanced their speed. MISHNA: The king “shall not accumulate many horses for himself” (Deuteronomy 17:16), but only enough for his chariot in war and in peace. “Neither shall he greatly accumulate silver and gold for himself” (Deuteronomy 17:17), but only enough to provide his soldiers’ sustenance [aspanya]. And the king writes himself a Torah scroll for his sake, as stipulated in Deuteronomy 17:18. When he goes out to war, he brings it out with him. When he comes in from war, he brings it in with him. When he sits in judgment, it is with him.

Type of Learning

Derash on the verse (Bavli sugya) — not a formal named middah of the 13

The Gemara uses this passuk inside a sugya (question, proof, or illustration). That is classical derash, but not labeled here as one of R' Yishmael’s 13 unless the move is explicit.

What Is Learned

‘Write for yourselves this song’ is a root of the mitzvah that each Jew be involved in writing a Sefer Torah: the Song is preserved as a witness in the mouth of the nation.
