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

5:13 When Ephraim saw his sickness, and Judah saw his wound, then went Ephraim to the Assyrian, and sent to king Jareb: yet could he not heal you, nor cure you of your wound.
