1 Samuel 18:1-5

1: 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: And Saul took him that day, and would not let him return to his father's house.

3: Then Jonathan made a covenant with David, because he loved him as his own soul.

4: And Jonathan stripped himself of the robe that was upon him, and gave it to David, and his armor, and even his sword and his bow and his girdle.

5: And David went out and was successful wherever Saul sent him; so that Saul set him over the men of war. And he was accepted in the sight of all the people and also in the sight of Saul's servants.
