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 9

9:4 They shall not offer wine offerings to the LORD, neither shall they be pleasing unto him: their sacrifices shall be unto them as the bread of mourners; all that eat thereof shall be polluted: for their bread for their soul shall not come into the house of the LORD.
