nActs 28:23b-27: From morning till evening he [Paul] explained and declared to them the kingdom of God and tried to convince them about Jesus from the Law of Moses and from the Prophets. Some were convinced by what he said, but other would
not believe. … (As the Holy Spirit through Isaiah said) “You will be ever hearing but never understanding; you will be ever seeing but never perceiving. For this people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes.”
