Some commentators suggest that the last five verses of the book of Amos were from a later prophet, because the hope expressed is in contrast to the disaster predicted in so many other utterances. There is no convincing reason why Amos should not have prophesied hope after the judgement, however. After Israel's sin has been punished, there will be a great restoration of the people under a new king of the line of David. The implication is that there will no longer be two divided kingdoms but a united people. Their lives will be rich with material blessings and they will be established in their land.
