Son of King Saul, and devoted friend of David, who was to succeed Saul and whom Jonathan protected from his father's jealous wrath (1 Sam. 19: 1–7; 20: 30). Indeed Saul was even jealous of Jonathan's military success against the Philistines (1 Sam. 14: 44). Jonathan and Saul were both killed and David is credited with a poignant lamentation for Jonathan (2 Sam. 1: 25–7).
