'Callous' in the Bible

They close up their callous hearts. With their mouth they speak proudly.

Their heart is as callous as the fat, but I delight in your law.

for this people's heart has grown callous, their ears are dull of hearing, they have closed their eyes; or else perhaps they might perceive with their eyes, hear with their ears, understand with their heart, and should turn again; and I would 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, and I would heal them.'

who having become callous gave themselves up to lust, to work all uncleanness with greediness.
