1 Chronicles 20:4-6

4After this, a war broke out with the Philistines at Gezer. At that time Sibbecai the Hushathite killed Sippai, a descendant of the Rephaim, and the Philistines were subdued.

5Once again there was a battle with the Philistines, and Elhanan son of Jair killed Lahmi the brother of Goliath of Gath. The shaft of his spear was like a weaver’s beam.

6There was still another battle at Gath where there was a man of extraordinary stature with six fingers on each hand and six toes on each foot — twenty-four in all. He, too, was descended from the giant.
