Mark 5:9

τί σοι ὄνομα; instead of saying at once what He had meant to say, Jesus adopts a roundabout method of dealing with the case, and asks the demoniac his name, as if to bring him into composure. Λεγιὼν : from the Roman legion not a rare sight in that region, emblem of irresistible power and of a multitude organised into unity; the name already naturalised into Greek and Aramaean. The use of it by the demoniac, like the immediate recognition of Jesus as a God-like person, reveals a sensitive, fine-strung mind wrecked by insanity.
