35 And He said to them, “When I sent you without money bag, knapsack, and sandals, did you lack anything?”
So they said, “Nothing.”
36 Then He said to them, “But now, he who has a money bag, let him take it, and likewise a knapsack; and he who has no sword, let him sell his garment and buy one. 37 For I say to you that this which is written must still be [a]accomplished in Me: ‘And He was numbered with the transgressors.’ For the things concerning Me have an end.”
38 So they said, “Lord, look, here are two swords.”
And He said to them, “It is enough.”
Luke 22:35-38
Jesus knows the road ahead for His disciples will be treacherous and challenging as they will be seen as transgressors. Where previously He sent them out with the clothes on their back, here he commands them to be prepared with money, supplies, and swords.
I don’t see Christ suggesting the weapons for offense, but possibly defense here, or even as tools for trade. Nobody was going to overthrow Rome or retake Jerusalem with a pair of swords, only the word of God could do that. Swords would be of no use, as evidenced by Peter’s actions in the garden of Gethsemane shortly after this section of scripture.
“…the things concerning Me have an end.” Even now as He prepares His disciples, the reality of what is in motion still evades them.
