The book of 2 Samuel describes a Giant with six fingers on each hand and six toes on each foot:
In still another battle, which took place at Gath, there was a huge man with six fingers on each hand and six toes on each foot—twenty-four in all. He also was descended from the Giants. When he taunted Israel, Jonathan son of Shimeah, David’s brother, killed him. (2 Sam. 21.20-21)
A Norwegian polydactylyphile by the name of Terje “Terry” Dahl has amassed a virtual statuary of six-fingered figures from around the world, which he believes furnishes evidence of the one-time ubiquity of Giants. You can view his collection on his website.
