<a href="http://bible.cc/isaiah/6-9.htm" ><b>9</b></a>And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not.
<a href="http://bible.cc/isaiah/6-10.htm" ><b>10</b></a>Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed.</p>
