Legion.
In the Roman army a body of troops consisting of from three to five thousand; but the term is also used for an indefinite number. The Lord said that His Father on His request would send Him more than twelve legions of angels. Matthew 26:53. The demons who possessed the man among the Gadarenes said, "My name is Legion; for we are many." Mark 5:9, Mark 1:5; Luke 8:30.
