Micah was a prophet of the eighth century BC, contemporary with Amos, Hosea, and Isaiah. As a prophet of the Southern Kingdom of Judah, he most closely resembles Isaiah. The book that bears his name does not all come from his hand. There is general agreement that his words are preserved in chapters 1 through 3 , probably also in chapter 6 , and in parts of chapter 7. Chapters 4 and 5 , however, were probably added after the Babylonian exile. The original words of Micah, like those of Amos, are largely preoccupied with issues of social justice and the coming Assyrian invasion.
