Isaiah 6:9-10

He said, “Go and tell this people: “‘Listen hard, but you aren’t going to get it; look hard, but you won’t catch on.’ Make these people blockheads, with fingers in their ears and blindfolds on their eyes, So they won’t see a thing, won’t hear a word, So they won’t have a clue about what’s going on and, yes, so they won’t turn around and be made whole.”
