From the Trivia Files: Riddle Me This

Jesus spoke in parables so that those who didn't want to listen to His message could persist in their stubbornness, quoting the prophecy in Isaiah which said:

"'Be ever hearing, but never understanding; be ever seeing, but never perceiving.'  Make the heart of this people calloused; make their ears dull and close their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and turn and be healed" (Isaiah 6: 9-10 NIV).

In essence, Christ often taught in riddles so that those who really wanted to know what He was talking about would actually ask.  Those who weren't humble enough to ask questions and accept the answers, never got them.  It was a way of getting people to pay attention.

There was one other person in the Bible who is on record for speaking to a crowd in riddles, although this individual's motives were not so pure.  Who was it?
