Isaías 6

9 And He said, Go, and tell this people:

Hear ye indeed, but understand not;

and see indeed, but perceive not.

10 Make the lev HaAm hazeh stubborn,

and make their ears stopped up,

their eyes heavy; lest they see with their eyes,

and hear with their ears,

and understand with their lev.

And have a spiritual turnaround conversion,

and be healed.
