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

5:5 And the pride of Israel doth testify to his face: therefore shall Israel and Ephraim fall in their iniquity; Judah also shall fall with them.
