'Foolish' in the Bible

Where is the wise? where scribe? where disputer of this world? has not God made foolish the wisdom of the world?

But God has chosen the foolish things of the world, that he may put to shame the wise; and God has chosen the weak things of the world, that he may put to shame the strong things;

Let no one deceive himself: if any one thinks himself to be wise among you in this world, let him become foolish, that he may be wise.
