The Philistines now mustered their army for battle and camped between Socoh in Judah and Azekah in Ephes-dammim. Saul countered with a buildup of forces at Elah Valley. So the Philistines and Israelis faced each other on opposite hills, with the valley between them. Then Goliath, a Philistine champion from Gath, came out of the Philistine ranks to face the forces of Israel. He was a giant of a man, measuring over nine feet tall! He wore a bronze helmet, a two-hundred-pound coat of mail, bronze leggings, and carried a bronze javelin several inches thick, tipped with a twenty-five-pound iron spearhead, and his armor bearer walked ahead of him with a huge shield. He stood and shouted across to the Israelis, “Do you need a whole army to settle this? I will represent the Philistines, and you choose someone to represent you, and we will settle this in single combat! If your man is able to kill me, then we will be your slaves. But if I kill him, then you must be our slaves! I defy the armies of Israel! Send me a man who will fight with me!” As Goliath approached, David ran out to meet him and, reaching into his shepherd’s bag, took out a stone, hurled it from his sling, and hit the Philistine in the forehead. The stone sank in, and the man fell on his face to the ground. So David conquered the Philistine giant with a sling and a stone. 1 Samuel 17:1-10; 48-50.
