Legion

Legion in the Topics

A regiment of the Roman army, the number of men composing which differed at different times. It originally consisted of three thousand men, but in the time of Christ consisted of six thousand, exclusive of horsemen, who were in number a tenth of the foot-men. The word is used (Matt 26:53; Mark 5:9) to express simply a great multitude.
