Saul spoke to Jonathan his son, and to all his servants, that they should kill David. But Jonathan, Saul's son, delighted much in David.
Jonathan’s appeal was successful, at least temporarily, and resulted in Saul solemnly vowing not to kill David (1 Samuel 19:6), which vow he broke shortly (1 Samuel 19:10). Later Jonathan was not as successful (1 Samuel 20:28-29). Nevertheless this time his appeal resulted in David’s restoration to the court and his continuing ministry to the king (1 Samuel 19:7).
