פירוש על בראשית 3:21

כתנות עור GARMENTS FOR THE SKIN — There are Agadoth which say that they were smooth as fingernails, cleaving to their skin; whereas some say that they were made of material that comes from skin, as for example, the hair of hares which is soft and warm, and of this He made garments for them (Genesis Rabbah 20:12).

כתנות עור וילבישם, coats, long enough to cover the whole body.

ויעש ...כתנות עור, without any input by man, similar to a description of the Talmud of what the earth will produce without human input in idyllic times when ready made bread rolls will be produced by the earth (Shabbat 30)
