Isaiah 6:9-10

Revised Standard Version Catholic Edition

‘Hear and hear, but do not understand;
see and see, but do not perceive.’
¹⁰ Make the heart of this people fat,
    and their ears heavy,
    and shut their eyes;
lest they see with their eyes,
    and hear with their ears,
and understand with their hearts,
    and turn and be healed.”
