'Crazy' in the Bible

They said to her, "You are crazy!" But she insisted that it was so. They said, "It is his angel."

As he thus made his defense, Festus said with a loud voice, "Paul, you are crazy! Your great learning is driving you insane!"

But he said, "I am not crazy, most excellent Festus, but boldly declare words of truth and reasonableness.

If therefore the whole assembly is assembled together and all speak with other languages, and unlearned or unbelieving people come in, won't they say that you are crazy?
