🔼The name Malchi-shua in the Bible
There's only one man in the Bible by the name Malchi-shua, and that is a son of Saul (1 Samuel 14:49, 1 Chronicles 8:33 & 9:39). Malchi-shua doesn't get much Biblical screen time. The only time his name appears not in a genealogy is when he dies by the hands of the Philistines on Mount Gilboa, along with his father and brothers Jonathan and Abinadab (1 Samuel 31:2, 1 Chronicles 10:2).
Note that this name Malchi-shua is spelled מלכי־שוע in Chronicles, but מלכישוע in Samuel.
