1 Samuel 17:52-58 - Israel Routs The Philistines
52 And the men of Israel and of Judah arose and shouted and followed after the Philistines, until they came to the valley and unto the gates of Ekron. And the Philistines fell down dead by the way, even unto Gath and Ekron.
53 And then the children of Israel returned from chasing after the Philistines and robbed their tents. 54 And David took the head of the Philistine and brought it to Jerusalem: But he put his armour in his tent.
55 When Saul saw David go forth against the Philistine, he said unto Abner the captain of his host, "Abner, whose son is this lad?" And Abner answered, "As truly as thy soul liveth, O king, I cannot tell."
56 Then said the king, "Enquire thou, whose son the youngling is."
57 And so when David was returned from the slaughter of the Philistine, Abner took him and brought him before Saul, with the head of the Philistine in his hand. 58 And Saul said to him, "Whose son art thou, thou lad?" And David answered, "The son of thy servant Jesse the Bethlehemite."
