In their case the prophecy of Isaiah is being fulfilled, which says,
‘YOU WILL KEEP ON HEARING, BUT WILL NOT UNDERSTAND;
YOU WILL KEEP ON SEEING, BUT WILL NOT PERCEIVE;
FOR THE HEART OF THIS PEOPLE HAS BECOME DULL,
WITH THEIR EARS THEY SCARCELY HEAR,
AND THEY HAVE CLOSED THEIR EYES,
OTHERWISE THEY WOULD SEE WITH THEIR EYES,
HEAR WITH THEIR EARS,
AND UNDERSTAND WITH THEIR HEART AND RETURN,
AND I WOULD HEAL THEM.’
But blessed are your eyes, because they see; and your ears, because they hear. For truly I say to you that many prophets and righteous men desired to see what you see, and did not see it, and to hear what you hear, and did not hear it.
“Hear then the parable of the sower. When anyone hears the word of the kingdom and does not understand it, the evil one comes and snatches away what has been sown in his heart. This is the one on whom seed was sown beside the road. The one on whom seed was sown on the rocky places, this is the man who hears the word and immediately receives it with joy; yet he has no firm root in himself, but is only temporary, and when affliction or persecution arises because of the word, immediately he falls away. And the one on whom seed was sown among the thorns, this is the man who hears the word, and the worry of the world and the deceitfulness of wealth choke the word, and it becomes unfruitful. And the one on whom seed was sown on the good soil, this is the man who hears the word and understands it; who indeed bears fruit and brings forth, some a hundredfold, some sixty, and some thirty.”
Jesus presented another parable to them, saying, “The kingdom of heaven may be compared to a man who sowed good seed in his field. But while his men were sleeping, his enemy came and sowed tares among the wheat, and went away.
