Matthew 13:11-13

Jesus answered, “The knowledge about the secrets of the Kingdom of heaven has been given to you, but not to them. For the person who has something will be given more, so that he will have more than enough; but the person who has nothing will have taken away from him even the little he has. The reason I use parables in talking to them is that they look, but do not see, and they listen, but do not hear or understand.
