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

2:7 And she shall follow after her lovers, but she shall not overtake them; and she shall seek them, but shall not find them: then shall she say, I will go and return to my first husband; for then was it better with me than now.
