A Roman legion consisted of about six thousand soldiers, or upwards; some add six hundred sixty six; and others make the number far greater. Twelve are mentioned, either with respect to the twelve apostles; or in allusion, as others think, to the Roman militia; a proper and full army with them consisting of such a number of legions: and that there is an innumerable company of angels, thousand thousands, and ten thousand times ten thousand, is certain; and the Persic version here reads; "twelve myriads" of legions; and that these are at the command of God, and he can dispatch them at once, on any emergent occasion, is very evident; and what is it that such a company of angels is not capable of, when a single angel slew in one night an hundred, fourscore, and five thousand men, ( 2 Kings 19:35 ) , wherefore had Christ had any inclination to have been rescued from the present danger, he stood in no need of Peter's sword.
