'Foolish' in the Bible

In all this Job did no sin, and did not say that God's acts were foolish.

And he said to her, You are talking like one of the foolish women. If we take the good God sends us, are we not to take the evil when it comes? In all this Job kept his lips from sin.

For wrath is the cause of death to the foolish, and he who has no wisdom comes to his end through passion.

I have seen the foolish taking root, but suddenly the curse came on his house.

He takes away the wisdom of the wise guides, and makes judges foolish;

Truly, you have all seen it yourselves; why then have you become completely foolish?
