'Obstinate' in the Bible

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.

But some grew obstinate in unbelief and spoke evil of the new faith before all the congregation. So Paul left them, and, taking with him those who were disciples, held discussions daily in Tyrannus's lecture-hall.

But as for Israel He says, “All the day long I have stretched out My hands to a disobedient and obstinate people.”

For we too once were foolish, disobedient, deceived, enslaved to various sinful desires and pleasures, spending and wasting our life in malice and envy, hateful, hating one another.
