'Legion' in the Bible

He was asking him, “What is your name?” And he replied, “My name is Legion; for we are many.”

They came to Jesus and saw the man who had been demon-possessed sitting down, clothed and in his right mind, the man who had [previously] had the “legion” [of demons]; and they were frightened.

Then Jesus asked him, “What is your name?” And he answered, “Legion”; because many demons had entered him.
