Is this saying really from Scriputre?

When I do open air preaching, one of the things I'll do to draw a crowd is to pull out my Glenn Beck-style blackboard and pick some folks off the street to play trivia. One of my favorites is a game where I ask people to identify the origin of popular sayings, ending up with sayings from the Bible that allow me to segue into the Gospel.

You'd be surprised how many people think that "a stitch in time saves nine" and "thou shalt tarry one hour before entering the waters after thy feast, lest thy muscles become weary and thou dost drown in the waters" come from the Bible (yes, people really did think the second one comes from the Bible), but don't know that "apple of my eye" and "a leopard cannot change his spots" really does.
