Elhanan the son of Jaare-oregim, the Bethlehemite
Israel slays four giant descendants slain, the second at Gob
Late in King David's reign, there was a series of wars between the Philistines and Israel in which David and his servants fell four descended from the giants in Gath. The third was at Gob, where Elhanan the son of Jaare-oregim, the Bethlehemite, struck down Goliath the Gittite, the shaft of whose spear was like a weaver's beam. (2 Samuel 21:15-22)
Elhanan the son of Dodo of Bethlehem
David's mighty men were divided into the three and the thirty. Elhanan the son of Dodo of Bethlehem is one of the thirty.
(2 Samuel 23:24)
