NASB
"The king said, "You inquire whose son the youth is.""
— 1 Samuel 17:56, NASB
“And the king said, Enquire thou whose son the stripling is.”
“And the king said, Inquire thou whose son the stripling is. ”
“The king said, "Inquire whose son the young man is!"”
“The king said,“Find out whose son this boy is!””
“And the king said: Inquire thou, whose son this young man is.”
“And the king said, Make search and see whose son this young man is.”
“And the king said, Enquire thou whose son the stripling is.”
The sons of Israel returned from chasing the Philistines and plundered their camps.
Then David took the Philistine's head and brought it to Jerusalem, but he put his weapons in his tent.
Now when Saul saw David going out against the Philistine, he said to Abner the commander of the army, "Abner, whose son is this young man?" And Abner said, "By your life, O king, I do not know."
The king said, "You inquire whose son the youth is."
So when David returned from killing the Philistine, Abner took him and brought him before Saul with the Philistine's head in his hand.
Saul said to him, "Whose son are you, young man?" And David answered, "I am the son of your servant Jesse the Bethlehemite."
