I heard from the Rebbe that in the days of Abraham the Shekhinah, Divine Presence, was called by the name of Sarah; in the days of Isaac by the name of Rebecca; and in the days of Jacob by the names of Rachel and Leah. (Likutei Halachos Basar v'Chalav, Halachah 2). And such is brought in the Holy Zohar (Breishit 112)
(קכ) שָׁמַעְתִּי מֵרַבֵּנוּ זִכְרוֹנוֹ לִבְרָכָה שֶׁבִּימֵי אַבְרָהָם אָבִינוּ הָיְתָה הַשְּׁכִינָה נִקְרֵאת בְּשֵׁם שָׂרָה, וּבִימֵי יִצְחָק בְּשֵׁם רִבְקָה, וּבִימֵי יַעֲקֹב בְּשֵׁם רָחֵל וְלֵאָה (הִלְכוֹת בָּשָׂר וְחָלָב הֲלָכָה ב). וְכֵן מוּבָא בַּזֹּהַר הַקָּדוֹשׁ (בְּרֵאשִׁית קיב.) מֵעֵין זֶה:
