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 10

10:5 The inhabitants of Samaria shall fear because of the calves of Bethaven: for the people thereof shall mourn over it, and the priests thereof that rejoiced on it, for the glory thereof, because it is departed from it.
