1 Samuel 17:53-55

New Century Version

⁵³ The Israelites returned after chasing the Philistines and robbed their camp. ⁵⁴ David took Goliath’s head to Jerusalem and put Goliath’s weapons in his own tent.

⁵⁵ When Saul saw David go out to meet Goliath, Saul asked Abner, commander of the army, “Abner, who is that young man’s father?”

Abner answered, “As surely as you live, my king, I don’t know.”
