'Stubborn' in the Bible

But because of your stubborn and unrepentant heart you are reserving wrath for yourself on the day of wrath, when God's righteous judgment will be revealed.

So then, He has mercy on whom He wills (chooses), and He hardens [the heart of] whom He wills.

But about Israel he says, "All day long I held out my hands to this disobedient and stubborn people!"
