I Sam. 17:1-58
The continuing conflict between Israel and the Philistines erupted again with the armies of each gathered on opposite mountains facing each other. There was a “champion” of the Philistines, a giant man of great height. He continually challenged the Israelites to send someone to meet him in a personal battle. The people of the one who would be killed would be servants of the other nation.
David’s father, Jesse had sent him to check on the welfare of his three oldest brothers. Upon hearing the challenge from the giant, he was disturbed that God’s armies were being defied and volunteered to face Goliath.
Saul was notified of David’s words and sent for him. Seeing that he was only a youth Saul initially rejected his offer, but David convinced him that the Lord would deliver him from Goliath.
The weight of Saul’s armor was so great that David could not walk. He removed them because, “I have not tested them.” Armed with his staff, sling and five smooth stones, he ran forward to face Goliath. In reply to the giant’s belittling remarks, David said, “You come to me with a sword, with a spear, and with a javelin. But I come to you in the name of the Lord of hosts…and He will give you into our hands.”
With the hurling of one stone that struck Goliath in the center of his forehead, the Lord delivered the Philistines into the hand of David. He used Goliath’s own sword and cut off his head and took it to Jerusalem as a trophy. David also took the giant’s armor as spoils of his victory.
Due to the possibility of an extended period of time between David’s service as harpist and the slaying of Goliath, Saul did not recognize him and inquired of his army commander, Abner who also did not know him. David later identified himself to the king.
