Goliath's Spear

There is a brief note about the exploits of David's men, which seems designed to show how well respected he was by them because remember David's awesome. Now one verse in this section here that's gotten a fair amount of attention has to do with Goliath. Despite protests from some well intended apologists, this story contradicts for Samuel 17 where Goliath also again described as having a spear shaft like a weaver's beam.
