'Dull' in the Bible

For the heart of this people has become dull,With their ears they scarcely hear,And they have closed their eyes,Otherwise they would see with their eyes,Hear with their ears,And understand with their heart and return,And I would heal them.’

For the heart of this people has become dull,And with their ears they scarcely hear,And they have closed their eyes;Otherwise they might see with their eyes,And hear with their ears,And understand with their heart and return,And I would heal them.”’

Concerning him we have much to say, and it is hard to explain, since you have become dull of hearing.
