1 Samuel 17:3-4, 8-11

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

And he stood and cried unto the armies of Israel, and said unto them, Why are ye come out to set your battle in array? am not I a Philistine, and ye servants to Saul? choose you a man for you, and let him come down to me. 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.
