“Then David took his staff in his hand. He chose five smooth stones from the brook. He put them in his shepherd’s bag, in the pouch. His sling was in his hand. He drew near to the Philistine. The Philistine came on and drew near to David, with his shield-bearer in front of him. When the Philistine looked and saw David, he disdained him. David was only a youth, ruddy and handsome in appearance. The Philistine said to David. ‘Am I a dog that you come to me with sticks?’ The Philistine cursed David by his gods. The Philistine said to David. ‘Come to me. I will give your flesh to the birds of the air and to the wild animals of the field.’ But David said to the Philistine. ‘You come to me with a sword, a spear, and a javelin. But I come to you in the name of Yahweh of hosts, the God of the armies of Israel, whom you have defied. This very day Yahweh will deliver you into my hand. I will strike you down. I will cut off your head. I will give the dead bodies of the Philistine’s army this very day to the birds of the air and to the wild animals of the earth. So that all the earth may know that there is a God in Israel. All this assembly may know that Yahweh does not save by the sword and spear. The battle is Yahweh’s. He will give you into our hand.’”
David goes out to meet Goliath. In this story he is not called Goliath, but Philistine. David had his staff, a sling shot, and pebbles in his pouch. Meanwhile the Philistine had a sword, a spear, and a javelin. They exchanged threats like wrestlers of today. The Philistine cursed David and resented being treated like a dog. Then David reminded him that Yahweh does not need these items of war. Interesting is the fact that they can communicate with each other. This assumes a common language, which I am not sure about.
