1 Samuel 17:40-42

He took his stick in his hand and chose five smooth stones from a stream. He put them in his shepherd’s bag and grabbed his sling. Then he went to meet the Philistine. At the same time, the Philistine was coming closer to David. The man who held his shield walked in front of him. When Goliath looked at David and saw that he was only a boy, tanned and handsome, he looked down on David with disgust.
