Acts 26:1-2, 24

Then Agrippa said unto Paul, Thou art permitted to speak for thyself. Then Paul stretched forth the hand, and answered for himself: I think myself happy, king Agrippa, because I shall answer for myself this day before thee touching all the things whereof I am accused of the Jews

And as he thus spake for himself, Festus said with a loud voice, Paul, thou art beside thyself; much learning doth make thee mad.
