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 5

5:9 Ephraim shall be desolate in the day of rebuke: among the tribes of Israel have I made known that which shall surely be.
