I Chronicles 20:4-8

Now it happened afterward that war broke out at Gezer with the Philistines, at which time Sibbechai the Hushathite killed Sippai, who was one of the sons of the giant. And they were subdued. Again there was war with the Philistines, and Elhanan the son of Jair killed Lahmi the brother of Goliath the Gittite, the shaft of whose spear was like a weaver’s beam. Yet again there was war at Gath, where there was a man of great stature, with twenty-four fingers and toes, six on each hand and six on each foot; and he also was born to the giant. So when he defied Israel, Jonathan the son of Shimea, David’s brother, killed him. These were born to the giant in Gath, and they fell by the hand of David and by the hand of his servants.
