[The idea of this essay is to answer a question that is sometimes brought up concerning the rabbit.]
[Actually I forget where that Rashi is. It might be at the verse of the covenant that God made with Avraham called ברית בין הבתרים. In any case it is a very famous Rashi.]
I should mention that you can see this kind of thing in the Gemara that says in the Sefer Torah of R. Meir it was written כתנות אור וילבישם not כתנות עור וילבישם as in the modern day version. That is: In the Torah scroll of R. Meir it says "God made for Adam and Eve shirts of light." Not "shirts of leather."
