Luke 22:38

And they said, Lord, behold, here are two swords. They did not understand the mind and words of Christ clearly. He did not mean that they should buy swords, but He wished to show them the impending danger. Christ did not explain His meaning to the Apostles, but concealed it, saying, "It is enough," meaning that Peter and the other Apostles might carry these swords, and even cut off Malchus' ear, which He Himself afterwards restored and healed, showing that He was not compelled by force, but was urged by love, willingly and freely to suffer and die. Some think that they were not military swords, but rather large butchers' knives, which the apostles used for the slaughtering, sacrificing, and disjointing of the Paschal Lamb. So S. Chrysostom, from whom I have said more on Matt. xxvii.

Ver. 39. And He came out, and went, as He was wont, to the mount of Olives. Bede gives the reason of this: "The Lord, when about to be delivered up, came to the retirement of this accustomed place, that He might be found the more easily. Where are they who maintained that He feared death, and was crucified against His will? Christ was wont, in these last days of His life, to preach in the temple by day, and to retire at night to the mount of Olives to pray. This, Judas, as being an Apostle, and a companion of Christ knew; and hence he came to this mountain with his followers, and there betrayed and delivered up Christ to them."
