John 18:3

And these men had often at other times sent to seize Him, but had not been able; whence it is plain, that at this time He voluntarily surrendered Himself. And how did they persuade the band? They were soldiers, who had made it their practice to do anything for money.

(Tr. cxii) It was a band not of Jews, but of soldiers, granted, we must understand, by the Governor, with legal authority to take the criminal, as He was considered, and crush any opposition that might be made.

"Judas then," he adds, "having received a cohort, and officers from the chief men and the Pharisees, cometh thither with lanterns, and torches, and weapons." It was a cohort, not of Jews, but of soldiers. We are therefore to understand it as having been received from the governor, as if for the purpose of securing the person of a criminal, and by preserving the forms of legal power, to deter any from venturing to resist his captors: although at the same time so great a band had been assembled, and came armed in such a way as either to terrify or even attack any one who should dare to make a stand in Christ's defense. For only in so far was His power concealed and prominence given to His weakness, that these very measures were deemed necessary by His enemies to be taken against Him, for whose hurt nothing would have sufficed but what was pleasing to Himself; in His own goodness making a good use of the wicked, and doing what was good in regard to the wicked, that He might transform the evil into the good, and distinguish between the good and the evil.

Judas knew that at the feast time our Lord was wont to teach His disciples high and mysterious doctrines, and that He taught in places like this. And as it was then a solemn season, he thought He would be found there, teaching His disciples things relating to the feast. They carry torches and lanterns, to guard against Christ escaping in the dark.

(Nihil tale in G.) The Evangelist had shown how Judas had found out the place where Christ was, now he relates how he went there. Judas then, having received a band of men and officers from the chief priests and Pharisees, cometh thither with lanterns and torches and weapons.
