This commentary interprets the first part of the book of Exodus, through 15:21. It features two approaches. On the one hand, the commentary interprets the final form of the traditional Hebrew text synchronically by means of form criticism and modern literary methods. On the other hand, it diachronically reconstructs the predecessors of the final form, from its origins in an exodus composition that opposes political domination to the text's final form as a dramatic narrative about the transfer of sovereignty from the Pharaoh to the God of Israel. Concluding syntheses examine the relationship between these two interpretive approaches while adding reflections on traditional and contemporary concerns.
