Genesis 3:21 Why leather garments?

[Zooey]

The leather garments seem to me, to look forward to the sacrifice of Christ. Another one of those fascinating “types” that serve to prophesy events of the New Testament.

You are correct.

Able gave from his best. Cain simply gave what he could spare. This reflected their internal attitudes.

I saw a TV program years ago, with an interfaith panel discussing the story of Cain & Abel, and the novelist Faye Kellerman ( a practicing religious Jew) explained that the Hebrew word for Cain’s gift was “lowly fruits”–just as you say, that it meant whatever he had that he could spare. (Like passing on something he was going to throw out anyway…)

 

[Jflores476]

One interpretation is that Adam and Eve were beings of light. The leather garments represent the mortal flesh that we take on after the fall.
