'Necks' in the Bible

But they didn't listen to me, and they didn't pay attention. They stiffened their necks, and they did more evil than their ancestors.

For this is what the LORD of the Heavenly Armies, the God of Israel, says: "I've put an iron yoke on the necks of all these nations to serve Nebuchadnezzar king of Babylon. They'll serve him, and I've even given the wild animals to him."'"
