QUESTIONS ON RASHI
Rashi writes: "Ki Yih'yeh Lahem Davar, Ba Elai' - [I.e.,] Whoever has a matter, he comes before me." What is bothering Rashi?
Gur Aryeh: The word "Lahem" us in plural - "when they have a matter [to adjucate];" yet the word "Ba" is in the singular - "he comes to me." Rashi explains that the plural to mean, "when any one member of the Klal has a matter, he comes before me...." 1
Why doesn't Rashi explain that the singular word "Davar" refers to the dispute - "... when they have a matter [of dispute], it comes before me? (See Ha'amek Davar, Malbim, etc).
