The prophet Micah lived at the time of the reigns of Jotham, Ahaz, and Hezekiah, kings of Judah.  His writings show a close relationship to those of Isaiah, who prophesied at a similar time.  His book appears to be a collection of oracles, delivered at different times and subsequently collected and written by the prophet of one of his disciples.  Micah speaks as a man of the people, with sympathy for the peasants and villagers and great concern for the political and social conditions of his people.  Micah addressed himself to the wrongs committed by the rulers and the wealthy, who lived in security while oppressing the poor.
