Rashi on Exodus 2:11/רש"י על שמות ב׳:י״א

1ויגדל 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 (Tanchuma Yashan 2.2:17; cf. also Yalkut Shimoni on Torah 166:11).

2וירא בסבלתם AND HE SAW THEIR BURDENS — he set his eyes and mind to share in their distress. (Exodus Rabbah 1:27)

3איש מצרי AN EGYPTIAN MAN — This was one of the taskmasters appointed over the Israelite officers and he used to rouse them from their beds at cock-crow that they might proceed to their work (Exodus Rabbah 1:28 and Leviticus Rabbah 32:4).

4מכה איש עברי SMITING A HEBREW MAN — beating and flogging him. The latter was the husband of Shelomith, the daughter of Dibri (see Leviticus 24:11), and the Egyptian taskmaster had set his fancy upon her. During the night he compelled him (her husband) to rise and made him leave the house. He, however, returned, entered the house and forced his attentions upon the woman, she believing it was her husband. The man returned and became aware of what had happened, and when the Egyptian perceived that he was aware of it he beat him and flogged him the whole day long (Exodus Rabbah 1:28).
