Hosea 9 & 10 are a sermon that Hosea delivered to the people of Israel at harvest time. This sermon summarizes several issues that Hosea has dealt with over and over again in the first eight chapters of the book. Once again he talks about the nation's tragic history of ingratitude and idolatry. He speaks of their loss of any sense of who they have been called to be and the certainty of God's chastening judgment.
