Acts 28:26-28

26“ ‘Go to this people and say, “You will be ever hearing but never understanding; you will be ever seeing but never perceiving.”

27For this people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts and turn, and I would heal them.’ Isaiah 6:9,10 (see Septuagint) 28“Therefore I want you to know that God’s salvation has been sent to the Gentiles, and they will listen!”
