'Obstinate' in the Bible

But Sihon king of Heshbon would not let us pass by him: for the LORD thy God hardened his spirit, and made his heart obstinate, that he might deliver him into thy hand, as appeareth this day.

And Jeshurun grew fat, and he kicked; you grew fat, you bloated, and you became obstinate; and he abandoned God, his maker, and he scoffed [at] the rock of his salvation.
