'Foolish' in the Bible

Where is the wise? Where is the scribe? Where is the lawyer of this world? Hasn't God made foolish the wisdom of this world?

but God chose the foolish things of the world that he might put to shame those who are wise. God chose the weak things of the world, that he might put to shame the things that are strong;

You foolish one, that which you yourself sow is not made alive unless it dies.
