They show when the passage is taken in context (Luke 22:36-38), Jesus is also aware of fulfilling prophecy and makes a surprising statement that two swords are "enough.
For I say to you that this which is written must still be accomplished in Me: ‘And He was numbered with the transgressors.’ For the things concerning Me have an end.” So they said, “Lord, look, here are two swords.” And He said to them, “It is enough.”Ellul, Yoder and Archie Penner claim that two swords could not possibly have been "enough" to defend Jesus from his pending arrest, trial and execution, so their sole purpose must have been Jesus' wish to fulfill a prophecy (Isaiah 53:9-12).
The warning had been given, and preparation for coming dangers hinted at; but as His meaning had not been apprehended in the comprehensive sense in which it was meant, He wished to leave the subject".
[5]Pope Boniface VIII referred to the two swords in the medieval papal bull Unam sanctam, to represent the temporal and spiritual authority of the church.
"[6] Theologian John Gill said in his Exposition of the Entire Bible: These words of Christ are not to be understood literally, that he would have his disciples furnish themselves with swords at any rate, since he would never have said, as he afterwards does, that two were sufficient; which could not be enough for eleven men; or have forbid Peter the use of one, as he did in a very little time after this: but his meaning is, that wherever they came, and a door was opened for the preaching of the Gospel, they would have many adversaries, and these powerful, and would be used with great violence, and be followed with rage and persecution; so that they might seem to stand in need of swords to defend them: the phrase is expressive of the danger they would be exposed to, and of their need of protection; and therefore it was wrong in them to be disputing and quarrelling about superiority, or looking out for, and expecting temporal pomp and grandeur, when this would be their forlorn, destitute, and afflicted condition; and they would quickly see the affliction and distress begin in himself.
