2 Samuel 21:18-19

21:18 Later there was another battle with the Philistines, this time in Gob. On that occasion Sibbekai the Hushathite killed Saph, who was one of the descendants of Rapha. 21:19 Yet another battle occurred with the Philistines in Gob. On that occasion Elhanan the son of Jair the Bethlehemite killed the brother of Goliath the Gittite, the shaft of whose spear was like a weaver’s beam.
