This book presents a new approach to the study of manna by showing interconnections between Ps 78:23-25, Wis 16:20-13; 19:21 and Jn 6:22-59. It asserts that Hellenistic Judaism is not "a second-class Judaism". This is proved with the example of manna, food of immortality, an idea introduced not in the Fourth Gospel, but already present in Wis 19:21
