'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.

But I say to you that everyone who is angry at his brother will be subject to judgment, and whoever says to his brother, 'Stupid fool!' will be subject to the council, and whoever says, 'Obstinate fool!' will be subject to fiery hell.
