'Neck' in the Bible

"But they and our fathers dealt proudly and hardened their neck, didn't listen to your commandments,

and refused to obey, neither were they mindful of your wonders that you did among them, but hardened their neck, and in their rebellion appointed a captain to return to their bondage. But you are a God ready to pardon, gracious and merciful, slow to anger, and abundant in loving kindness, and didn't forsake them.

and testified against them, that you might bring them again to your law. Yet they dealt proudly, and didn't listen to your commandments, but sinned against your ordinances, (which if a man does, he shall live in them), turned their backs, stiffened their neck, and would not hear.
