‘Keep on listening, but do not understand;
Keep on looking, but do not comprehend.’

“Make the heart 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.”

²¹ 
‘Now hear this, O foolish people without heart,
Who have eyes but do not see,
Who have ears but do not hear.^(A)
