Peter wielded an actual sword in Gethsemane. He and the other Disciples had swords. Because Jesus commanded them to buy them.
Of course we're free to not own weapons. But,it isn't what Jesus taught us.
And what happened when Peter used his sword? Jesus rebuked him.
Why did Jesus say to buy a sword, then say two was enough?
The two swords were not for self defense or for killing those who attack. Two swords would not be nearly enough to combat the Roman soldiers who were coming to arrest Jesus.
In fact, when Peter used his sword to cut off someone’s ear, Jesus healed the ear and scolded Peter to put away his sword.
Jesus condemned weaponry by saying that all who use the sword will perish by the sword.
Those two swords were enough for Jesus to be reckoned among the transgressors. The Roman soldiers could see the swords and arrest Jesus for being an instigator of armed rebellion against the empire.
"Jesus reckoned among the transgressors" refers to the fulfillment of prophecy (Isaiah 53:12) where Jesus was treated, condemned, and executed as a common criminal, specifically by being crucified between two thieves. This act represents his deep identification with sinful humanity, substituting himself in the place of sinners to achieve atonement and reconciliation with God.
Luke 22
36 Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
37 For I say unto you, that this that is written must yet be accomplished in me, And he was reckoned among the transgressors: for the things concerning me have an end.
38 And they said, Lord, behold, here are two swords. And he said unto them, It is enough.
Matthew 26:52
Then said Jesus unto him, “Put up again thy sword into his place, for all they that take the sword shall perish with the sword.”
John 18:36
Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence.
