A recent article posted on the Biblical Archaeology Society’s site about left-handed people in the Bible put a smile on my face.
The article makes a good observation:
The Hebrew Bible mentions left-handed people on three occasions: the story of Ehud’s assassination of the Moabite king (Judges 3:12–30), the 700 Benjamites who could use the sling with deadly accuracy (Judges 20:16) and the two-dozen ambidextrous warriors who came to support David in Hebron (1 Chronicles 12:2). All of these stories of left-handed people in the Bible appear in military contexts, and, curiously, all involve members of the tribe of Benjamin.
The thing which looks to me to be intentionaly humorous is that all these left-handed men are from the tribe of Benjamin, and Benjamin means “son of my right hand“! There has to be an intentional, and possibly humorous, play on Benjamin’s name there.
In fact, the Bible has so many stories which refer specifically to meanings of names it seems fairly obvious that in some of these stories the name was actually made up to fit the story, or to ridicule a character. For example, in 1 Samuel 25:25 there is an incident concerning Nabal where his wife says: “My lord, do not take seriously this ill-natured fellow, Nabal; for as his name is, so is he; Nabal is his name, and folly is with him”.
In Hebrew Nabal נָבָל (pronounced Naval) means “foolish”, “worthless” or “good for nothing”.  Since it is unlikely his parents hated him so much as to call him “fool” from birth, so scholars discuss how the name might also be understood according to an alternative Semitic root meaning “noble.” The meaning “fool” would be a play on the double meaning of the name. Zeev Weisman deals specifically with the case of Naval as one of several pejorative names which ridiculed and smeared the bearers, noting that there is also a phonic association between the name Naval and the wordנַבֶל (navel) wineskin which may be behind the account of Naval’s death: “In the morning, when the wine had gone out of Naval [like an empty wineskin, a navel], his wife told him these things, and his heart died within him”(36-37). 
There is certainly some wordplay going on here, and wordplay in the Hebrew Bible is often not just a case of being clever with words, but also of being playful with words in order to ridicule a character or simply to inject some humour in to the story.
