1 Chronicles 20:4-8

Later, at Gezer, war broke out with the Philistines. Sibbecai the Hushathite killed Sippai, who was one of the descendants of the Rephaites. So those Philistines were defeated. Later, there was another battle with the Philistines. Elhanan son of Jair killed Lahmi, the brother of Goliath, who was from the town of Gath. His spear was as large as a weaver’s rod. At Gath another battle took place. A huge man was there; he had six fingers on each hand and six toes on each foot—twenty-four fingers and toes in all. This man also was one of the sons of Rapha. When he spoke against Israel, Jonathan son of Shimea, David’s brother, killed him. These descendants of Rapha from Gath were killed by David and his men.
