Question:

Who is the shortest man in the Bible?

Answer:

There are all sorts of jokes based on this question, but I will assume you are looking for a more serious answer.

We actually don't know since height isn't always mentioned. We know that Zacchaeus was short: "Now behold, there was a man named Zacchaeus who was a chief tax collector, and he was rich. And he sought to see who Jesus was, but could not because of the crowd, for he was of short stature" (Luke 19:2-3). But this only tells us that he was shorter than average, which is why he could not see over the crowd gathering around Jesus.
