John 18:3

A band - Την σπειραν , The band or troop. Some think that the spira was the same as the Roman cohort, and was the tenth part of a legion, which consisted sometimes of 4200, and sometimes of 5000 foot. But Raphelius, on Matthew 27:27 , has clearly proved, from Polybius, that the spira was no more than a tenth of the fourth part of a legion. And as the number of the legion was uncertain, and their divisions not at all equal, no person can tell how many the band or spira contained. See many curious particulars in Raphelius on this point, vol. i. p. 351, edit. 1747. This band was probably those Roman soldiers given by the governor for the defense of the temple; and the officers were those who belonged to the Sanhedrin.

With lanterns and torches - With these they had intended to search the corners and caverns, provided Christ had hidden himself; for they could not have needed them for any other purpose, it being now the fourteenth day of the moon's age, in the month Nisan, and consequently she appeared full and bright. The weapons mentioned here were probably no other than clubs, staves, and instruments of that kind, as we may gather from Matthew 26:55 ; Mark 14:48 ; Luke 22:52 . The swords mentioned by the other evangelists were probably those of the Roman soldiers; the clubs and staves belonged to the chief priest's officers.
