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 5

5:8 Blow ye the cornet in Gibeah, and the trumpet in Ramah: cry aloud at Bethaven, after thee, O Benjamin.
