1 Samuel 18:1-3
After David had finished speaking with Saul, the souls of Jonathan and David were knit together, and Jonathan loved him as himself. And from that day Saul kept David with him and did not let him return to his father’s house. Then Jonathan made a covenant with David because he loved him as himself.
