Jonathan, in the Hebrew Bible (Old Testament) books 1 and 2 Samuel, the eldest son of King Saul. Jonathan’s intrepidity and fidelity to his friend, the future king David, make him one of the most admired figures in the Bible. Jonathan is first mentioned in 1 Samuel 13:2, when he defeated a garrison of Philistines at Geba. Later (1 Samuel 14), Jonathan and his armour-bearer left Saul’s army at Geba and captured the outpost at Michmash. The Israelites then attacked and defeated the Philistines.
Possibly because of his piety, Saul then ordered a fast for one day, but the absent Jonathan was unaware of the order and ate wild honey. When Saul requested information about the war from God and there was no answer, Saul blamed the silence on Jonathan’s breaking of the fast and would have killed him had not his own soldiers ransomed Jonathan.
When David became a member of Saul’s household and won many victories against the Philistines, he and Jonathan became close friends. After Saul jealously turned against David, Jonathan attempted to reconcile them, but he was only briefly successful. Saul tried to enlist Jonathan’s aid to kill David, but Jonathan remained David’s friend and warned him of Saul’s anger so that David hid. When the two met for the last time in the Wilderness of Ziph, they planned that David would be the next king of Israel and Jonathan his minister (1 Samuel 23:16–18).
Saul, Jonathan, and Jonathan’s brothers were killed in a battle against the Philistines at Mount Gilboa. Despoiled and exposed by the Philistines, the bodies were rescued by men from Jabesh-Gilead and buried in Jabesh. Years later, David reinterred the remains in the tomb of Kish in the land of Benjamin. David lamented the deaths of Saul and Jonathan in a moving elegy (2 Samuel 1:17–27).
