David and Jonathan were, according to the Hebrew Bible's Books of Samuel, heroic figures of the Kingdom of Israel, who formed a covenant, taking a mutual oath.
Jonathan was the son of Saul, king of Israel, of the tribe of Benjamin, and David was the son of Jesse of Bethlehem, of the tribe of Judah, and Jonathan's presumed rival for the crown. David became king. The covenant the two men had formed eventually led to David, after Jonathan's death, graciously seating Jonathan's son Mephibosheth at his own royal table instead of eradicating the former king Saul's line.
The biblical text does not explicitly depict the nature of the relationship between David and Jonathan. The traditional and mainstream religious interpretation of the relationship has been one of platonic love and an example of homosociality. Some scholars and writers—late Middle Ages and onwards—have emphasized what they see as elements of homoeroticism in the story.
