Isaiah 6:8-10 NIV
Then I heard the voice of the Lord saying, “Whom shall I send? And who will go for us?”
And I said, “Here am I. Send me!”
He said, “Go and tell this people:
“ ‘Be ever hearing, but never understanding;
be ever seeing, but never perceiving.’
Make the heart of this people calloused;
make their ears dull
and close their eyes.
Otherwise they might see with their eyes,
hear with their ears,
understand with their hearts,
and turn and be healed.”
NIV: New International Version
