Matthew 13:11-13

¹¹ He replied, “Because the knowledge of the secrets of the kingdom of heaven has been given to you, but not to them. ¹² Whoever has will be given more, and they will have an abundance. Whoever does not have, even what they have will be taken from them. ¹³ This is why I speak to them in parables:

“Though seeing, they do not see;
    though hearing, they do not hear or understand.
