'Foolish' in the Bible

Where [is] the wise person? Where [is] the scribe? Where [is] the debater of this age? Has not God made foolish the wisdom of the world?

But the foolish [things] of the world God chose in order that he might put to shame the wise, and the weak [things] of the world God chose in order that he might put to shame the strong,

Foolish person! What you sow does not come to life unless it dies.
