1 Chronicles 20:4-6

4Now it came about after this, that war broke out with the Philistines at Gezer. Then Sibbecai the Hushathite struck down Sippai, one of the descendants of the Rephaim, and they were subdued.

5Again there was war with the Philistines, and Elhanan the son of Jair killed Lahmi, the brother of Goliath the Gittite, whose spear had a shaft like a weaver’s beam.

6Once again there was a battle at Gath, where there was a man of great stature who had 24 fingers and toes, six on each hand and six on each foot. He too also descended from the giants.
