Then the disciples came to him and said, Why do you speak to them in parables?” He replied, “You have been given the opportunity to know the secrets of the kingdom of heaven, but they have not. For whoever has will be given more, and will have an abundance. But whoever does not have, even what he has will be taken from him. For this reason I speak to them in parables: Although they see they do not see, and although they hear they do not hear nor do they understand. (Matthew 13:10–13 NET)
