Now do not stiffen your neck like your fathers, but yield to the Lord and enter His sanctuary which He has consecrated forever, and serve the Lord your God, that His burning anger may turn away from you.

He also rebelled against King Nebuchadnezzar who had made him swear allegiance by God. But he stiffened his neck and hardened his heart against turning to the Lord God of Israel.
