1 Chronicles 20:3-7
English Standard Version
4And after this there arose war with the Philistines at Gezer. Then Sibbecai the Hushathite struck down Sippai, who was one of the descendants of the giants, and the Philistines were subdued.
5And there was again war with the Philistines, and Elhanan the son of Jair struck down Lahmi the brother of Goliath the Gittite, the shaft of whose spear was like a weaver 's beam.
6And there was again war at Gath, where there was a man of great stature, who had six fingers on each hand and six toes on each foot, twenty-four in number, and he also was descended from the giants.
7And when he taunted Israel, Jonathan the son of Shimea, David 's brother, struck him down.
