their hearts might understand and they might repent and be healed.”

and hear with their ears

and understand with their hearts

and turn, and I would heal them.’

and they have closed their eyes,

so that they would not see with their eyes

and hear with their ears

and understand with their heart

and turn, and I would heal them.”’
