Isaías 6:8-12 - Bíblia Online

And the voice of the Lord came to my ears, saying, Whom am I to send, and who will go for us? Then I said, Here am I, send me. 
And he said, Go, and say to this people, You will go on hearing, but learning nothing; you will go on seeing, but without getting wiser. 
Make the hearts of this people fat, and let their ears be stopped, and their eyes shut; for fear that they may see with their eyes, and be hearing with their ears, and their heart may become wise, and they may be turned to me and made well. 
Then I said, Lord, how long? And he said in answer, Till the towns are waste and unpeopled, and the houses have no men, and the land becomes completely waste, 
And the Lord has taken men far away, and there are wide waste places in the land.
