Rashi on Exodus 2:13/רש"י על שמות ב׳:י״ג

1שני אנשים עברים TWO MEN OF THE HEBREWS — viz., Dathan and Abiram (Nedarim 64b); it was they, too, who left over some of the manna (Exodus Rabbah 1:29).

2נצים means quarelling.

3למה תכה lit., WHEREFORE WILT THOU SMITE — Although he had not yet smitten him he is termed here רשע wicked, because he had merely raised his hand against him (Sanhedrin 58b).

4רעך THY FELLOW (the word denotes one who is the equal of another) — who is as wicked as yourself (Exodus Rabbah 1:29).
