The Action Bible gives an exciting and dramatic retelling of 2 Samuel 2-3. It basically recounts some of the war between David and Saul's son Ish-Bosheth. The commanders of the two armies decide to have each of their 10 strongest warriors fight each other, to save casualties. (Remember this is family fighting family.) However, the small battle turns into a larger chase and David's army wins. Abner, who had been the commander of Ish-Bosheth's army, decided he was on the wrong side and changed to support David.
A simple game of chase was our activity today. Though we did not run with spears as they did in the story :)
