I Samuel 17:3-4, 8-11

The Philistines stood on a mountain on one side, and Israel stood on a mountain on the other side, with a valley between them. And a champion went out from the camp of the Philistines, named Goliath, from Gath, whose height was six cubits and a span.

Then he stood and cried out to the armies of Israel, and said to them, “Why have you come out to line up for battle? Am I not a Philistine, and you the 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 be your servants. But if I prevail against him and kill him, then you shall 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 these words of the Philistine, they were dismayed and greatly afraid.
