The Rephaite were a race of demi-giants found in Biblical lore, they were among the "smallest" of the giant types believed to have regularly warred with the early Hebrew people, with other giant-like races described in such texts including the Anakim and Nephilim.
History[]
The Rephaite were a tribe of giants found in the Bible who stood much larger than an average human and often quarrelled with the early Hebrew people; the most infamous of all the Rephaite would be Og, a mythological king who was said to be so large, his bed was over 9 cubits in length (roughly equal to 14 ft (4 meters) in today's standards).
Goliath is also considered to have likely been a Rephaite due to his relatively "small" size but some believe him to be a member of the Anakim (or even a completely unique figure unrelated to either tribe).
