The Holy Bible - David - A Young Hero

Twice a day for 40 days, Goliath, the champion of the Philistines, comes out between the lines and challenges the Israelites to send out a champion of their own to decide the outcome in single combat. However, Saul and all the other Israelites are afraid of him. David is present, having brought food for his elder brothers. Told that Saul has promised to reward any man who defeats Goliath, David accepts the challenge. Saul reluctantly agrees and offers his armor, which David declines, taking only his sling and five stones chosen in a brook.
