The king (Saul) tried to give David some equipment. "What do you want, boy? Shield? Sword? Grenades? Rifles? A helicopter?"
David had something else in mind. Five smooth stones and an ordinary leather sling.
The soldiers gasped. Saul sighed. Goliath jeered. David swung. And God made His point.
Anyone who underestimates what God can do with the ordinary has rocks in his head!
