Micah prophesied sometime between 750 and 686 B.C. during the reigns of Jotham, Ahaz, and Hezekiah, kings of Judah. Israel was in an apostate condition. Micah predicted the fall of her capital, Samaria, and also foretold the inevitable desolation of Judah.
Micah was raised up to support Isaiah, and to confirm his predictions, while he invited to repentance, both by threatened judgments and promised mercies. A very remarkable passage, Micah 5 contains a summary of prophecies concerning the Messiah.
