Amos 6:14

"For the Lord God Almighty declares, 'I will stir up a nation against you, Israel, that will oppress you all the way from Lebo Hamath to the valley of the Arabah.'" NIV translation

Once again, Amos shares the judgment of God. 

Lebo Hamath would be northern Lebanon and the valley of the Arabah would be the Dead Sea area. 

This shows that the judgment will be on all of Israel. It also hints at the fact that Assyria would be the tool used for the coming judgment.
