'Obstinate' in the Bible

But Sihon king of Heshbon was not willing to let us cross through his [territory] because Yahweh your God hardened his spirit and {made him obstinate} {in order to give him} into your hand, {just as he has now done}.

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.

because {I know} that you [are] obstinate, and your neck an iron sinew, and your forehead bronze.
