Thematic Bible: That blindness fulfilled

And not agreeing among themselves, they departed, after Paul had spoken one word: Well did the Holy Spirit speak to our fathers by Isaiah the prophet, saying: Go to this people and say, You shall surely hear, but you will not understand; and you shall surely see, but you will not perceive. For the heart of this people has become fat, and with their ears they hear heavily, and their eyes they have closed, lest they should see with their eyes, and hear with their ears, and understand with their heart, and should turn, and I should restore them to health.
