Jonathan (1 Samuel) in Wikipedia

Jonathan (Hebrew: יְהֹונָתָן Yəhōnāṯān or Yehonatan) is a heroic figure in 1 Samuel in the Hebrew Bible. He was the son of King Saul and close friend of King David. The relationship between David and Jonathan is one of the most notable biblical relationships. Jonathan first appears in the biblical narrative as the victor of Geba, a Philistine stronghold (1 Samuel 13), and dies tragically at Mount Gilboa along with his father and brothers (1 Samuel 31). Jonathan was the father of Mephibosheth.
