Isaiah 6:9-10

⁹He said, “Go, and tell this people:

‘Keep on listening, but do not perceive;
Keep on looking, but do not understand.’
¹⁰“Render the hearts of this people insensitive,
Their ears dull,
And their eyes dim,
Otherwise they might see with their eyes,
Hear with their ears,
Understand with their hearts,
And return and be healed.”
