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

9:12 Though they bring up their children, yet will I bereave them, that there shall not be a man left: yea, woe also to them when I depart from them!
