1 Samuel 17:48-50 New International Reader's Version (NIRV)

48. As the Philistine moved closer to attack him, David ran quickly to the battle line to meet him.

49. He reached into his bag. He took out a stone. He put it in his sling. He slung it at Goliath. The stone hit him on the forehead and sank into it. He fell to the ground on his face.

50. So David won the fight against Goliath with a sling and a stone. He struck the Philistine down and killed him. He did it without even using a sword.
