8Then I heard the voice of the Lord saying:

“Whom shall I send? Who will go for Us?”

And I said: “Here am I. Send me!”

9 And He replied:

“Go and tell this people,

‘Be ever hearing, but never understanding; be ever seeing, but never perceiving.’

10 Make the hearts of this people calloused; deafen their ears and close their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and turn and be healed.”. Isaiah 6.8-10
