¹¹He replied, "The knowledge of the secrets of the kingdom of heaven has been given to you, but not to them. ¹²Whoever has will be given more, and he will have an abundance. Whoever does not have, even what he has will be taken from him. ¹³This is why I speak to them in parables:
"Though seeing, they do not see;
though hearing, they do not hear or understand. ¹⁴In them is fulfilled the prophecy of Isaiah:
" 'You will be ever hearing but never understanding;
you will be ever seeing but never perceiving.
¹⁵For this people's heart has become calloused;
they hardly hear with their ears,
and they have closed their eyes.
Otherwise they might see with their eyes,
hear with their ears,
understand with their hearts
and turn, and I would heal them. ¹⁶But blessed are your eyes because they see, and your ears because they hear. ¹⁷For I tell you the truth, many prophets and righteous men longed to see what you see but did not see it, and to hear what you hear but did not hear it.

¹⁸"Listen then to what the parable of the sower means: ¹⁹When anyone hears the message about the kingdom and does not understand it, the evil one comes and snatches away what was sown in his heart. This is the seed sown along the path. ²⁰The one who received the seed that fell on rocky places is the man who hears the word and at once receives it with joy. ²¹But since he has no root, he lasts only a short time. When trouble or persecution comes because of the word, he quickly falls away.²²The one who received the seed that fell among the thorns is the man who hears the word, but the worries of this life and the deceitfulness of wealth choke it, making it unfruitful. ²³But the one who received the seed that fell on good soil is the man who hears the word and understands it. He produces a crop, yielding a hundred, sixty or thirty times what was sown."
