Never Understanding

"you will be ever hearing but never understanding;
You will be ever seeing but never perceiving.
For this people's heart has become calloused;
They hardly hear with their ears,
And they have closed their eyes.
Otherwise they might see with their eyes,
Hear with their ears,
Understand with their hearts
And turn, and i would heal them. but blessed are your eyes
Because they see, and your ears because they hear. for i tell
You the truth, many prophets and righteous men longed to see
What you see but did not see it, and to hear what you hear but
Did not hear it."
