2 Samuel 21:20-22

20And 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.

21And when he taunted Israel, Jonathan the son of Shimei, David's brother, struck him down.

22These four were descended from the giants in Gath, and they fell by the hand of David and by the hand of his servants.
