Isaiah 29:10-13

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.

11You do not understand this vision that the Lord has given to me. It is like the words in a closed book. Give the book to someone who can read. Say to him, ‘Read this, please.’ But he will answer, ‘I cannot read it, because someone has closed it.’

12Give the book to someone who cannot read and tell them, ‘Read it, please.’ But he will answer, ‘I do not know how to read.’

13The Lord God says, ‘These people open their mouths to worship me. They use their lips to say that I am great. But they are not really thinking about me. When they worship me, they use rules that people have taught them.
