Scholarship on Judaic friendship in the Medieval period is not prolific, as this chapter discusses. The value of kinship is thought to override friendship values. In the Old Testament of the Bible, however, there are some significant friendships, such as the relationship between Jonathan and David; between Ruth and Naomi; and some analyses also refer to the friendship between God and Moses. Jewish writers in the Medieval period were influenced by, and in turn had an influence on, Christian and Islamic scholarship on friendship. This chapter looks for references to friendship in the philosophical work of these Jewish sages, from Philo of Alexandria in the first century AD to Moses de Léon in the thirteenth century. While two books of the Hebrew Bible are named for women—Ruth and Ester—there are claims that ‘alone of the Abrahamic traditions, Judaism has excluded women from its mystical tradition’ (Raphael 2021). Women’s role was largely confined to wifedom.
