'Stiff' in the Bible

yet they didn't listen to me, nor inclined their ear, but made their neck stiff: they did worse than their fathers.

But they didn't listen, neither turn their ear, but made their neck stiff, that they might not hear, and might not receive instruction.

Thus says Yahweh of Armies, the God of Israel, Behold, I will bring on this city and on all its towns all the evil that I have pronounced against it; because they have made their neck stiff, that they may not hear my words.
