Hosea is the first book of the twelve minor prophets. Because the times are outwardly prosperous, idolatry prevails and immorality is rampant. Hosea urges a return to God in order that He may show mercy and forgiveness.

Hosea 9

9:7 The days of visitation are come, the days of recompense are come; Israel shall know it: the prophet is a fool, the spiritual man is mad, for the multitude of thine iniquity, and the great hatred.
