'Callous' in the Bible

For this people’s heart has grown callous;their ears are hard of hearing,and they have shut their eyes;otherwise they might see with their eyesand hear with their ears,understand with their heartsand turn back—and I would cure them.

For the hearts of these peoplehave grown callous,their ears are hard of hearing,and they have shut their eyes;otherwise they might see with their eyesand hear with their ears,understand with their heart,and be converted,and I would heal them.

They became callous and gave themselves over to promiscuity for the practice of every kind of impurity with a desire for more and more.
