'Stubbornness' in the Bible

Remember your servants, Abraham, Isaac, and Jacob; you must not {pay attention to} the stubbornness of this people, to their wickedness and to their sin,

And then when he hears the words of this oath, then {he will assure himself} in his heart, {saying}, '{Safety shall be mine even though I go in the stubbornness of my heart},' thereby destroying the well-watered [land] [along] with the parched.
