This paper intends to introduce Robert Cover’s theory of radical pluralism by underlining the powerful connections between his scholarship and his lifelong study of Jewish texts. In some of his published works, Cover’s extensive knowledge of and reliance on Jewish sources is evident. The paper enucleates three main “Jewish” themes in Cover’s work. These are: 1) the idea of the social order of groups as universe composed of nomos and narrative; 2) the idea that obligation represents the force of gravity that keeps together social orders; 3) the idea that law can be an instrument of change, even when it is the expression of a messianic movement. In the latter case, an example from Jewish history, i.e. the attempt to renew Semikah in Safed, is taken as a test case for Cover’s theory.
