ACT 26:24

24 When he spake these things, and yielded reason, Festus said with (a) great voice, Paul, thou maddest, [[or Paul, thou waxest (or thou growest) mad]]; many letters turn thee to madness. (And when he had said these things, and made his defence, Festus said with a loud voice, Paul, thou art mad; too much study hath driven thee mad.)
