Suppose the Bible they hand you to swear on is upside down, or backward, or both, and you swear to tell the truth on an upside-down backward Bible. Would that count? Suppose the Bible they hand you is an old Bible and half the pages are missing. Suppose all they have is a Chinese Bible. In an American court. Or a Braille Bible, and you're not blind. Suppose they hand you an upside-down, backward, Chinese, Braille Bible with half the pages missing.
