Acts 28:27

For this people’s heart has grown callous; 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.’

Note Isaiah 6:9–10 (see also LXX)

For the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed; lest they should see with their eyes, and hear with their ears, and understand with their heart, and should be converted, and I should heal them.

For this people’s heart has grown callous. Their ears are dull of hearing. Their eyes they have closed. Lest they should see with their eyes, hear with their ears, understand with their heart, and would turn again, then I would heal them.’

For this people’s heart is waxed gross, And their ears are dull of hearing, And their eyes they have closed; Lest haply they should perceive with their eyes, And hear with their ears, And understand with their heart, And should turn again, And I should heal them.
