'Foolish' in the Bible

But he said unto her, Thou speakest as one of the foolish women speaketh. What? shall we receive good at the hand of God, and shall we not receive evil? In all this did not Job sin with his lips.

For vexation killeth the foolish man, And jealousy slayeth the silly one.

I have seen the foolish taking root: But suddenly I cursed his habitation.
