It’s the original underdog story. The enemy Philistines stand before King Saul and the Israelites in the Valley of Elah. For weeks, the massive Philistine warrior Goliath calls for the Israelites to send out a challenger. Saul is afraid, but offers a reward to anyone willing to fight Goliath. The young David hears and accepts. He declined the king’s armor and takes only his staff, a slingshot and five smooth stones.
