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 7

7:1 When I would have healed Israel, then the iniquity of Ephraim was discovered, and the wickedness of Samaria: for they commit falsehood; and the thief cometh in, and the troop of robbers spoileth without.
