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 6

6:9 And as troops of robbers wait for a man, so the company of priests murder in the way by consent: for they commit lewdness.
