וַיִּקְרָ֨א פַרְעֹ֣ה שֵׁם־יוֹסֵף֮ צָֽפְנַ֣ת פַּעְנֵ֒חַ֒ וַיִּתֶּן־ל֣וֹ אֶת־אָֽסְנַ֗ת בַּת־פּ֥וֹטִי פֶ֛רַע כֹּהֵ֥ן אֹ֖ן לְאִשָּׁ֑ה וַיֵּצֵ֥א יוֹסֵ֖ף עַל־אֶ֥רֶץ מִצְרָֽיִם׃
And Pharaoh called Yosef’s name Zaphenath-paneah; and he gave him to wife Asenath the daughter of Poti-phera priest of On. And Yosef went out over the land of Egypt.
Classical midrashic tradition on the name and the marriage (Bereshit Rabbah and parallel sources).
Sefaria · Bereshit Rabbah 90 (context)
צָפְנַת פַּעְנֵחַ – מְפָרֵשׁ הַצְּפוּנוֹת. אָסְנַת בַּת פּוֹטִי פֶרַע – יֵשׁ אוֹמְרִים שֶׁהָיְתָה מִזֶּרַע יוֹסֵף עַצְמוֹ בְּדֶרֶךְ נֵס.
English of Core Text: “Zaphenath-paneah” — interpreter of the hidden things. Asenath daughter of Poti-phera — some say she was of the seed of Yosef himself by miraculous means (or, in other classical readings, that she converted and became a fitting match).
On the daf / in context: The midrashic literature explores both the Egyptian name given to Yosef (revealer of secrets) and the identity of Asenath, ensuring that the matriarch of Ephraim and Menasheh is presented in a manner consistent with the later status of the tribes.
Type of Learning: Derash on the verse (classic midrash) — not a formal named middah of the 13.
What Is Learned: The name Pharaoh gave Yosef acknowledges his unique ability to reveal what is hidden, and the tradition surrounding Asenath safeguards the legitimacy of the two tribes that descend from her.
