1 Samuel 17:50-52

New Century Version

⁵⁰ So David defeated the Philistine with only a sling and a stone. He hit him and killed him. He did not even have a sword in his hand. ⁵¹ Then David ran and stood beside him. He took Goliath’s sword out of its holder and killed him by cutting off his head.

When the Philistines saw that their champion was dead, they turned and ran. ⁵² The men of Israel and Judah shouted and chased the Philistines all the way to the entrance of the city of Gath and to the gates of Ekron.

The Philistines’ bodies lay on the Shaaraim road as far as Gath and Ekron.
