'Foolish' in the Bible

Is this how you repay the Lord,you foolish and senseless people?Isn’t He your Father and Creator?Didn’t He make you and sustain you?

They have provoked My jealousywith their so-called gods;they have enraged Me with their worthless idols.So I will provoke their jealousywith an inferior people;I will enrage them with a foolish nation.
