Isaiah 29:9-10

9You are so surprised that you do not believe what I say. You have become completely blind. You are stupid, like people who are drunk, but not from wine! You fall over, but not because you have drunk too much beer!

10It is the Lord who has caused you to be like that. He has caused you to be completely asleep. He has shut the eyes of your prophets and he has covered the heads of your seers.
