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

10:9 O Israel, thou hast sinned from the days of Gibeah: there they stood: the battle in Gibeah against the children of iniquity did not overtake them.
