1 Chronicles 20:6-8

And there was again war at Gath, where there was a man of great stature, who had six fingers on each hand and six toes on each foot, twenty-four in number, and he also was descended from the giants. And when he taunted Israel, Jonathan the son of Shimea, David’s brother, struck him down. These were descended from the giants in Gath, and they fell by the hand of David and by the hand of his servants.
