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 8

8:13 They sacrifice flesh for the sacrifices of mine offerings, and eat it; but the LORD accepteth them not; now will he remember their iniquity, and visit their sins: they shall return to Egypt.
