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 8

8:6 For from Israel was it also: the workman made it; therefore it is not God: but the calf of Samaria shall be broken in pieces.
