בהית הבקר. מְלַמֵּד שֶׁהִקְדִּים עַל יָדָם, מַה שֶּׁאֵין דֶּרֶךְ בָּשָׂר וָדָם לַעֲשׂוֹת כֵּן – שֶיְּהֵא הָרַב מַמְתִּין לַתַּלְמִיד; וְכֵן מָצִינוּ "קוּם צֵא אֶל הַבִּקְעָה, וָאָקוּם וָאֵצֵא אֶל הַבִּקְעָה וְהִנֵּה שָׁם כְּבוֹד ה' עֹמֵד" (יחזקאל ג'):

בהיות הבקר lit., WHEN IT WAS BEING MORNING — This phrase tells us that He was there before them at the place of the Divine Revelation, something which it is not customary for human beings to do — that the teacher should await the arrival of his disciple. A similar instance we find in Scripture (Ezekiel 3:22, 23): “[God said unto me]. Arise, go forth into the plain, [and I will there speak with thee]. Then I arose, and went forth into the plain; and, behold the glory of the Lord stood there already” (Midrash Tanchuma, Ki Tisa 15; cf. Nedarim 8a).
