'Wits' in the Bible

They reel to and fro, and stagger like a drunken man, and are at their wits' end.

When Jesus saw that he answered thoughtfully and intelligently, He said to him, “You are not far from the kingdom of God.” And after that, no one would dare to ask Him any more questions.

I repeat then, let no one think that I am foolish; but even if you do, at least accept me as foolish, so that I too may boast a little.
