1 Samuel 18:1-4 - The Friendship Of David And Jonathan
1 Now after David's talk with Saul was ended, the soul of Jonathan was joined with the soul of David, and David became as dear to him as his very life. 2 And that day Saul took David and would not let him go back to his father's house.
3 Then Jonathan and David made an agreement together, because of Jonathan's love for David. 4 And Jonathan took off the robe he had on and gave it to David, with all his military dress, even to his sword and his bow and the band round his body.
