1 Samuel 18:1-7

After David had finished talking with Saul, Jonathan became one in spirit with David, and he loved him as himself. From that day Saul kept David with him and did not let him return home to his family. And Jonathan made a covenant with David because he loved him as himself. Jonathan took off the robe he was wearing and gave it to David, along with his tunic, and even his sword, his bow and his belt. Whatever mission Saul sent him on, David was so successful that Saul gave him a high rank in the army. This pleased all the troops, and Saul’s officers as well. When the men were returning home after David had killed the Philistine, the women came out from all the towns of Israel to meet King Saul with singing and dancing, with joyful songs and with timbrels and lyres. As they danced, they sang: “Saul has slain his thousands, and David his tens of thousands.”
