1 Samuel 18:3-5

Living Bible

18 ^1-3 After King Saul had finished his conversation with David, David met Jonathan, the king’s son, and there was an immediate bond of love between them. Jonathan swore to be his blood brother, ⁴ and sealed the pact by giving him his robe, sword, bow, and belt.

King Saul now kept David with him and wouldn’t let him return home anymore. ⁵ He was Saul’s special assistant, and he always carried out his assignments successfully. So Saul made him commander of his troops, an appointment that was applauded by the army and general public alike.
