When the Israelites came back from their pursuit of the Philistines, they looted all the goods in the Philistine camp.
David took the Philistine's head and brought it to Jerusalem, but he kept Goliath's armor in his tent.
As Saul watched David going out against the Philistine, he asked Abner, the commander of the army, "Abner, whose son is this young man?" Abner answered, "I solemnly swear, as you live, Your Majesty, I don't know."
The king said, "Find out whose son this young man is."
When David returned from killing the Philistine, Abner brought him to Saul. David had the Philistine's head in his hand.
Saul asked him, "Whose son are you, young man?" "The son of your servant Jesse of Bethlehem," David answered.
