'Defense' in the Bible

"Men--brothers and fathers--listen to my defense to you now!"

[while] Paul said in his defense, "Neither against the law of the Jews nor against the temple nor against Caesar have I sinned with reference to anything!"

And [as] he was saying these things in his defense, Festus said with a loud voice, "You are out of your mind, Paul! [Your] great learning {is driving} you {insane}!"
