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 12

12:14 Ephraim provoked him to anger most bitterly: therefore shall he leave his blood upon him, and his reproach shall his Lord return unto him.
