1 Samuel 17:9-11

If he be able to fight with me, and to kill me, then will we be your servants: but if I prevail against him, and kill him, then shall ye be our servants, and serve us. And the Philistine said, I defy the armies of Israel this day; give me a man, that we may fight together. When Saul and all Israel heard those words of the Philistine, they were dismayed, and greatly afraid.
