Isaiah 6:9-10

He said, “Go and tell this people:

“‘Be ever hearing, but never understanding;
be ever seeing, but never perceiving.’
¹⁰ 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.”

Romans 11:25, 28-32
