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 2

2:16 And it shall be at that day, saith the LORD, that thou shalt call me Ishi; and shalt call me no more Baali.
