Isaiah 5

Six times in this passage Isaiah proclaims sorrow upon the people of Judah. There is not one word of commendation; nothing praiseworthy is passed on by God. I wonder if the words Isaiah spoke described attitudes he already recognized in Judah or were these new revelations to the prophet? Could he name the people upon whom he spoke these sorrows beforehand, or was he surprised to see who was guilty as they squirmed angerly when he spoke God's words? For a man who was familar with the happenings in Jerusalem how much of this prophecy had been hidden from his sight? I guess I would expect Isaiah to shake his head in disbelief when God described the hidden rebellion that was active in the city that bore his holy name.
It took me about 5 minutes to read this chapter.
