1 Samuel 18:1-3

Saul Comes to Fear David

18:1 When David had finished talking with Saul, Jonathan and David became bound together in close friendship. Jonathan loved David as much as he did his own life. 18:2 Saul retained David on that day and did not allow him to return to his father’s house. 18:3 Jonathan made a covenant with David, for he loved him as much as he did his own life.
