1 Samuel 17:57--18:2

17:57 So when David returned from striking down the Philistine, Abner took him and brought him before Saul. He still had the head of the Philistine in his hand. 17:58 Saul said to him, “Whose son are you, young man?” David replied, “I am the son of your servant Jesse in Bethlehem.”

Saul Comes to Fear David

18:1 When David had finished talking with Saul, Jonathan and David became bound together in close friendship. Jonathan loved David as much as he did his own life. 18:2 Saul retained David on that day and did not allow him to return to his father’s house.
