The book of Isaiah reflects many of the population movements that took place in the period of its formation. Much biblical scholarship focuses on “the (Babylonian) Exile,” but as C. L. Crouch points out in “Isaiah and Migration,” mass population movements were carried out in the sphere of Israel and Judah by the Assyrians long before the Babylonians overthrew Jerusalem. She also calls attention to the migrations experienced by other nations, and to forces of displacement other than deportation, such as warfare, famine, and natural disasters. She analyzes the literary reception of these numerous involuntary migrations, and the ways in which the prophet and his audiences made sense of them.
