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 13

13:1 When Ephraim spake trembling, he exalted himself in Israel; but when he offended in Baal, he died.
