1 Samuel 17:8-11

He stood and shouted to the ranks of Israel and said to them, “Why do you come out to draw up in battle array? Am I not the Philistine and you servants of Saul? Choose a man for yourselves and let him come down to me. If he is able to fight with me and kill me, then we will become your servants; but if I prevail against him and kill him, then you shall become our servants and serve us.” Again the Philistine said, “I defy the ranks of Israel this day; give me a man that we may fight together.” When Saul and all Israel heard these words of the Philistine, they were dismayed and greatly afraid.
