Son of Saul, crown prince of Israel. He made a covenant of loyalty with David that cost him the throne. When Saul hunted David, Jonathan protected him at the risk of his own life. He was killed alongside Saul at the battle of Gilboa. David lamented him: "your love to me was wonderful, surpassing the love of women."
On their voice
~1050 BCE. A man of extraordinary personal loyalty who made a choice between his father and his covenant friend that is almost unprecedented in the biblical narrative. He knew David would be king; he helped it happen at the cost of his own succession.
