(יא) ויגדל משה. וַהֲלֹא כְּבָר כָּתַב וַיִּגְדַּל הַיֶּלֶד? אָמַר רַבִּי יְהוּדָה בְּרַבִּי אִלְעָאִי, הָרִאשׁוֹן לְקוֹמָה וְהַשֵּׁנִי לִגְדֻלָּה, שֶׁמִּנָּהוּ פַּרְעֹה עַל בֵּיתוֹ (ילקוט שמעוני):
(יב) וירא בסבלתם. נָתַן עֵינָיו וְלִבּוֹ לִהְיוֹת מֵצֵר עֲלֵיהֶם (שמות רבה א'):
(11) ויגדל משה AND MOSES WAS GROWN — But has it not already been written, (Exodus 2:10) “And the child grew”? Rabbi Judah the son of Eloai said: the first time it refers to growth in stature, the second time to greatness, — that Pharaoh appointed him to have charge over his palace.
(12) וירא בסבלתם AND HE SAW THEIR BURDENS — he set his eyes and mind to share in their distress.
(יב) ויפן כה וכה. רָאָה מֶה עָשָׂה לוֹ בַּבַּיִת וּמֶה עָשָׂה לוֹ בַשָּׂדֶה (שם). וּלְפִי פְּשׁוּטוֹ כְּמַשְׁמָעוֹ:
(12) ויפן כה וכה AND HE TURNED THIS WAY AND THAT WAY — he saw what he had done to him in the house and what he had done to him in the field (outside the house. viz., the beating to which he had subjected him) (Exodus Rabbah 1.28). But according to the literal meaning it must be explained in its ordinary sense: he turned this way and that way.
Aryeh Bernstein, JewSchool
Fugitive Moses is tending his sheep, when an unusual thing catches his eye: “He gazed, and there was a bush, all aflame, yet the bush was not consumed. Moses said, ‘I must turn aside to look at this marvelous sight; why doesn’t the bush burn up?’Although the reader already knows that this is a sign from God (v. 1), Moses does not. He just thinks it’s interesting. We see unusual things all the time, but how often do we pay attention to them? More often, we ignore them, explain them away, or feel too busy tending our sheep to investigate. Had Moses not been driven by a need to understand, he never would have had the chance to hear God’s voice. Note the language: “When YHWH saw that he had turned aside to look, God called to him” (v. 4). It is Moses’s expression of intellectual curiosity that justifies calling him and giving him the job. Strategizing within the well-defined parameters of the task at hand does not cut it: one must be constantly studying the entire world; after all, the source for solving the greatest national problems might lie in an unusual, small bush.

Similarly it is written in the holy book, Beit Avraham (P. Vayikra) commenting on the verse He called to Moses; Hashem spoke to him…that Moses was able to hear the voice of Hashem calling to him in every situation. Sometimes the message came in the form of flowing kindness; sometimes in the form of severity, but it was always by Divine providence from his Father in Heaven speaking to him, calling him to be at one with Blessed Hashem.
