'Mad' in the Bible

And they said to her, Thou art mad. But she maintained that it was so. And they said, It is his angel.

And as he answered for his defence with these things, Festus says with a loud voice, Thou art mad, Paul; much learning turns thee to madness.

But Paul said, I am not mad, most excellent Festus, but utter words of truth and soberness;

If therefore the whole assembly come together in one place, and all speak with tongues, and simple persons enter in, or unbelievers, will not they say ye are mad?
