I suspect most folks know and can tell some version of the story of David and Goliath (see 1 Samuel 17). It is a narrative that lends itself to story telling for people of all ages.  It is also a story that is so familiar that when we attempt to study the biblical passage we are likely to engage in isogesis, placing our interpretation upon the text, rather than exegesis, letting the story inform us. I regularly lead a bible study with emphasis on “study.”  I think the line I most often use is some variation of “Is that what the text says?”

With that as background, have a look at the ever interesting Malcolm Gladwell’s talk on David and Goliath
