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 12

12:2 The LORD hath also a controversy with Judah, and will punish Jacob according to his ways; according to his doings will he recompense him.
