New King James Version (NKJV)
1 Samuel 17
52 Now the men of Israel and Judah arose and shouted, and pursued the Philistines as far as the entrance of the valley and to the gates of Ekron. And the wounded of the Philistines fell along the road to Shaaraim, even as far as Gath and Ekron.
53 Then the children of Israel returned from chasing the Philistines, and they plundered their tents.
54 And David took the head of the Philistine and brought it to Jerusalem, but he put his armor in his tent.
55 When Saul saw David going out against the Philistine, he said to Abner, the commander of the army, "Abner, whose son is this youth?" And Abner said, "As your soul lives, O king, I do not know."
56 So the king said, "Inquire whose son this young man is."
57 Then, as David 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 are you, young man?" So David answered, "I am the son of your servant Jesse the Bethlehemite."
1 Samuel 18
1 Now when he had finished speaking to Saul, the soul of Jonathan was knit to the soul of David, and Jonathan loved him as his own soul.
2 Saul took him that day, and would not let him go home to his father’s house anymore.
3 Then Jonathan and David made a covenant, because he loved him as his own soul.
4 And Jonathan took off the robe that was on him and gave it to David, with his armor, even to his sword and his bow and his belt.
