'Foolish' in the Bible

[Like] this do you treat Yahweh, foolish and {unwise} people? [Has] he not, your father, created you? He made you, and he established you.

They annoyed me with [what is] not a god; they provoked me with their idols. So I will make them jealous with [those] not a people, with a foolish nation I will provoke them.
