Hosea warned Israel of coming destruction due to their lack of knowledge of God's will and rejection of his prophets. They had committed grievous sins like idolatry, injustice, and immorality while still offering sacrifices. Their leaders and priests had become corrupt. God called them to repentance through Hosea, but if they did not turn from their sins, punishment would come. Amos similarly preached to Israel around 760 BC, calling them to repent from sins like greed, oppression of the poor, and hypocrisy. Though prosperous, Amos prophesied Israel would be destroyed if they did not repent, likening their fate to scraps left from a lion's meal.
