This punishment will be widespread around the world -- Amos begins with specific warnings for several nations. However, it will be most severe for Israel and Judah. These are God's chosen people, whom God has nurtured, protected, and guided for generations, but they have turned their backs on God (even though they should have known better).
No one can escape this judgment, which will cause widespread suffering and destruction. However, like other prophets, Amos does foresee a time after "the day of the Lord" when God will restore the chosen people to the Promised Land, where they will enjoy the fruits of God's goodness and favor again.
