According to the author of 1 Chronicles, there was a big fight in a place called Gath, where they met a giant man with six fingers on each hand and six toes on each foot, and he was part of a family of big giants. This shows that there were very strong and unusual people back then.
1 Chronicles 20:6: And yet again there was war at Gath, where was a man of [great] stature, whose fingers and toes [were] four and twenty, six [on each hand], and six [on each foot]: and he also was the son of the giant. [great...: Heb. measure] [the son...: Heb. born to the giant, or, Rapha]
Describes a similar event with a giant with six fingers and toes, but it occurs in Gath, which can be seen as a contradiction in the location or context of the events described.
2 Samuel 21:20: And there was yet a battle in Gath, where was a man of [great] stature, that had on every hand six fingers, and on every foot six toes, four and twenty in number; and he also was born to the giant. [the giant: or, Rapha]
