'Calloused' in the Bible

They are calloused; they speak arrogantly.

Their hearts are calloused, but I find delight in your law.

Make the hearts of these people calloused; make their ears deaf and their eyes blind! Otherwise they might see with their eyes and hear with their ears, their hearts might understand and they might repent and be healed."

“For the heart (the understanding, the soul) of this people has become dull (calloused),And with their ears they scarcely hear,And they have shut their eyes [to the truth];Otherwise they might see with their eyes,And hear with their ears,And understand with their heart and return [to Me],And I would heal them.”’

But [in fact] their minds were hardened [for they had lost the ability to understand]; for until this very day at the reading of the old covenant the same veil remains unlifted, because it is removed [only] in Christ.
