"This book represents engaged scholarship at its very best. Cohen presents the vast range of texts at his command with brevity and wit. Elegantly written, this is a very stimulating book that is sure to provoke admiration, discussion, and controversy."--David Biale, author of Cultures of the Jews "A distinguished and wide-ranging work of scholarship. Cohen's definitive discussion of the covenant of circumcision enhances our understanding of Jewish identity formation, women's status in Judaism, Jewish-Christian polemic, and the impact of diverse cultural environments on the evolution of Jewish tradition."--Judith R. Baskin, author of Midrashic Women.
