We continue to find ourselves assaulted by the words of Amos as they press upon the pride of Jacob as being the downfall of the people of Israel. Again, the issue with those who do not follow or obey the way of the Lord is because the people of God have turned toward idols and have not maintained their faithful devotion to God.
We read a few times the prophet say "Alas", and that is for the state that the people of God are in. He especially is speaking out against the ruling class, those who are "at ease" and have the ability to lie on beds of ivory and sing idle songs, you know, the type that David used to sing but not nearly as good. As a result of their complacency they are going to be the first to go into exile (vs.7).
What we find here is really one recognition of how God has turned his back on His people time after time simply because the people of God have turned their back on Him time after time. I think all you need to hear is the last verse which states: "Indeed, I am raising up against you a nation, O house of Israel, says the Lord, the God of hosts, and they shall oppress you from Lebo-hamath to teh Wadi Arabah." Now, those are fighting words.
