The Talmud derives from the Torah's language of marriage ('he takes a wife') that a man may marry multiple women, though a woman may not have multiple husbands — establishing the biblical permissibility of polygamy that Rabbeinu Gershom's later ban addressed.
וְאִי בָּעֵית אֵימָא: הָא מַנִּי – רַבִּי שִׁמְעוֹן הִיא, דְּתַנְיָא, רַבִּי שִׁמְעוֹן אוֹמֵר: מִפְּנֵי מָה אָמְרָה תּוֹרָה ״כִּי יִקַּח אִישׁ אִשָּׁה״, וְלֹא כָּתַב ״כִּי תִּלָּקַח אִשָּׁה לְאִישׁ״? – מִפְּנֵי שֶׁדַּרְכּוֹ שֶׁל אִישׁ לְחַזֵּר עַל אִשָּׁה וְאֵין דַּרְכָּהּ שֶׁל אִשָּׁה לְחַזֵּר עַל אִישׁ. מָשָׁל לְאָדָם שֶׁאָבְדָה לוֹ אֲבֵידָה – מִי חוֹזֵר עַל מִי? בַּעַל אֲבֵידָה מְחַזֵּר עַל אֲבֵידָתוֹ.
And if you wish, say instead: In accordance with whose opinion is this mishna, which teaches derekh? It is in accordance with the opinion of Rabbi Shimon, as it is taught in a baraita that Rabbi Shimon says: For what reason did the Torah say: “When a man takes a woman” (Deuteronomy 22:13) and did not write: “When a woman is taken by a man? Because it is the way [derekh] of a man to pursue a woman, and it is not the way of a woman to pursue a man. The Gemara cites a parable of a man who lost an item. Who searches for what? Certainly the owner of the lost item searches for his lost item, not the other way around. Since woman was created from man’s lost side, the man seeks that which he has lost. To allude to this statement of Rabbi Shimon, the mishna employs the term derekh in this context.
