Why does Jesus tell the Apostles told to buy swords?

[Michele_Boyer]

I’m very confused by Luke 22:23 where Jesus tells the Apostles to go buy swords if they don’t have one. Some say this is figurative for preparing to battle spiritually, but that doesn’t really make sense. It also doesn’t make sense that Jesus would tell them to buy weapons, especially since He corrected Peter for cutting the soldier’s ear off. What exactly does this verse mean. Here it is in context:
Instructions for the Time of Crisis.
35 He said to them, “When I sent you forth without a money bag or a sack or sandals, were you in need of anything?” “No, nothing,” they replied.
36 He said to them,* “But now one who has a money bag should take it, and likewise a sack, and one who does not have a sword should sell his cloak and buy one.
37 For I tell you that this scripture must be fulfilled in me, namely, ‘He was counted among the wicked’; and indeed what is written about me is coming to fulfillment.”x
38 Then they said, “Lord, look, there are two swords here.” But he replied, “It is enough!”*

 

[Fr.Charles_Grondin]

It is generally understood that Jesus was speaking figuratively but that the apostles understood him literally, thus Jesus ends the discussion abruptly.

Jesus was explaining to them the need to be prepared for opposition from the world to their message. The Apostles, misunderstanding Jesus as usual, thought Jesus was speaking about literally gathering up swords. When they say to him they already have two swords, Jesus abruptly ends the discussion since they apparently missed the point. The fact that Jesus said only two swords were enough for the 11 reinforced that he was speaking metaphorically.
