King James Version (KJV)
They have not known nor understood: for he hath shut their eyes, that they cannot see; {and} their hearts, that they cannot understand. {shut: Heb. daubed}
Modern English
They don’t know, neither do they consider: for he has shut their eyes, that they can’t see; and their hearts, that they can’t understand.
Hebrew
