Exodus 2:14

מי שמך לאיש WHO MADE THEE A PERSONAGE (lit., a man), and you are yet only a boy (Midrash Tanchuma, Shemot 10). הלהרגני אתה אמר lit. WILT THOU SPEAK IN ORDER TO SLAY ME — From this we may learn that he had killed him by the mere utterance of the “Shem Hamephorash” (Midrash Tanchuma, Shemot 10; Exodus Rabbah 1:30). ויירא משה AND MOSES FEARED — Explain it in its literal sense: he was afraid of Pharaoh. A Midrashic explanation is: he felt distressed because he saw that there were wicked men among the Israelites — common informers. He said: Since this is so (מעתה), perhaps they are not worthy to be delivered from bondage (Midrash Tanchuma, Shemot 10). אכן נדע הדבר SURELY THE THING IS KNOWN — Explain it in its literal sense: the fact that I have killed the Egyptian is known. A Midrashic explanation is: now there is known to me that matter about which I have been puzzled — how has Israel sinned more than all the seventy nations, that they should be oppressed by this crushing servitude? But now I see that they deserve this (Exodus Rabbah 1:30).

וַ֠יֹּ֠אמֶר מִ֣י שָֽׂמְךָ֞ לְאִ֨ישׁ שַׂ֤ר וְשֹׁפֵט֙ עָלֵ֔ינוּ הַלְהׇרְגֵ֙נִי֙ אַתָּ֣ה אֹמֵ֔ר כַּאֲשֶׁ֥ר הָרַ֖גְתָּ אֶת־הַמִּצְרִ֑י וַיִּירָ֤א מֹשֶׁה֙ וַיֹּאמַ֔ר אָכֵ֖ן נוֹדַ֥ע הַדָּבָֽר׃

And he said, Who made thee a prince and a judge over us? dost thou intend to kill me, as thou didst kill the Miżrian? And Moshe feared, and said, Surely this thing is known.
