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 2

2:11 I will also cause all her mirth to cease, her feast days, her new moons, and her sabbaths, and all her solemn feasts.
