1 Samuel 18:1-4 New Revised Standard Version (NRSV)
Jonathan’s Covenant with David
18 When David[a] had finished speaking to Saul, the soul of Jonathan was bound to the soul of David, and Jonathan loved him as his own soul. 2 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 Jonathan stripped himself of the robe that he was wearing, and gave it to David, and his armor, and even his sword and his bow and his belt.
