In this chapter we hear a song of a vineyard -- a vineyard prepared by God with every thing needed for success. But, the only yield was bitter grapes.  The hearers of this are then invited into the story:  "What more could I've done?", God asks.  The answer comes quickly and in the form of judgment and curse.

There's a description of various "woes" that follow -- evidences of how crazy things have become now that the people have rebelled against the Lord. 

The chapter closes with the sound of hoofbeats -- the army that is coming at God's command!
