Matthew 13:13-15
13:13 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.
13:14 And concerning them the prophecy of Isaiah is fulfilled that says: ‘You will listen carefully yet will never understand,
you will look closely yet will never comprehend.
13:15 For the heart of this people has become dull;
they are hard of hearing,
and they have shut their eyes,
so that they would not see with their eyes
and hear with their ears
and understand with their hearts
and turn, and I would heal them.’
Matthew 13:19
13:19 When anyone hears the word about the kingdom and does not understand it, the evil one comes and snatches what was sown in his heart; this is the seed sown along the path.
