Matthew 13:11-13

And he answered and said unto them, Unto you it is given to know the mysteries of the kingdom of heaven, but to them it is not given. For whosoever hath, to him shall be given, and he shall have abundance: but whosoever hath not, from him shall be taken away even that which he hath. Therefore speak I to them in parables; because seeing they see not, and hearing they hear not, neither do they understand.
