'Stiffened' in the Bible

“But they, our fathers, acted arrogantly;They stiffened their necks and would not heed Your commandments.

“They refused to listen and obey,And did not remember Your wondrous acts which You had performed among them;So they stiffened their necks and [in their rebellion] appointed a leader in order to return them to slavery in Egypt.But You are a God of forgiveness,Gracious and merciful and compassionate,Slow to anger and abounding in lovingkindness;And You did not abandon them.

You warned them to turn back to Your law,but they acted arrogantlyand would not obey Your commands.They sinned against Your ordinances,which a person will live by if he does them.They stubbornly resisted,stiffened their necks, and would not obey.
