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 10

10:1 Israel is an empty vine, he bringeth forth fruit unto himself: according to the multitude of his fruit he hath increased the altars; according to the goodness of his land they have made goodly images.
