1 Chronicles 20:4-8

Later war broke out with the Philistines at Gezer. That was the time Sibbecai the Hushathite killed Sippai of the clan of giants. The Philistines had to eat crow. In another war with the Philistines, Elhanan son of Jair killed Lahmi, the brother of Goliath the Gittite whose spear was like a ship’s boom. And then there was the war at Gath that featured a hulking giant who had twenty-four fingers and toes, six on each hand and foot—yet another from the clan of giants. When he mocked Israel, Jonathan son of Shimea, David’s brother, killed him. These came from the clan of giants and were killed by David and his men.
