I Chronicles 20:6-8

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.
