Matthew 13:11-13

He replied, “You are permitted to understand the secrets of the Kingdom of Heaven, but others are not. To those who listen to my teaching, more understanding will be given, and they will have an abundance of knowledge. But for those who are not listening, even what little understanding they have will be taken away from them. That is why I use these parables, For they look, but they don’t really see. They hear, but they don’t really listen or understand.
