How about "blessed are the peacemakers"?
How about "they shall beat their swords into plowshares"?
I didn't see many commentaries or pastors who shared your viewpoint about the luke passage, I however have acquired quite a few that support my premises:
Other commentators who believe in a literal Luke 22:36:
----------------------------------------
And he said unto them, But now, he that hath a purse, let him take it, and likewise a wallet; and he that hath none, let him sell his cloak, and buy a sword.
The absolute pacifist tradition among Christians of all ages and the acceptance of it by many commentators make this verse "a real problem" for many. Most commentators view the passage as figurative, as did Geldenhuys, who said, "The Lord intended (these words) in a figurative sense."[19] But if the sword is figurative, what about the purse, the wallet, and the cloak?
As Hobbs said, "It is impossible to tone down this statement; neither can we dismiss it as not being a genuine saying of Jesus."[20] The clear meaning of the passage is that "a sword" is the one thing needful, even surpassing in priority such an important item as a cloak. The two errors to be avoided here are (1) the supposition that the gospel should be spread by the sword, and (2) the notion that a sword should ever be employed against lawful authority. Before the evening was over, the Lord would have further occasion to demonstrate the proper and improper uses of the sword. Barnes was certainly correct in his view that "These directions (concerning the sword) were not made with reference to his being taken in the garden but to their future lives."[21]
J. S. Lamar, an eminent Restoration scholar, expressed surprise "to find several of the ablest Protestant expositors interpreting (this passage) as a warrant for self-defense."[22] Nevertheless, the view maintained here is that self-defense is exactly what Jesus taught. Self-defense is a basic, natural right of all men, and there is no lawful government on earth that denies it. Just why should it be supposed that Jesus denied to Christians such a basic right has never been explained. "Resist not evil ... go the second mile ... turn the other cheek... give thy cloak also, etc." are not applicable to situations in which one's life is threatened, or endangered.

We are living in difficult days. The Lord said, “He that hath no sword, let him sell his garment, and buy one.” Why? For self protection, of course. They were living in days that required a sword. We need to recognize that fact also. If we do not resist evil today, all kinds of evil will befall us. We could end up in the hospital or have some of our loved ones slain.

22:36. Jesus’ instructions here reflect the culmination of His mission and the crescendo of antagonism from the leadership in Jerusalem. The increased context of hostility called for supplies that would facilitate self-preservation (a “money bag” or knapsack) and self defense (a sword). Although the supplies would change, they would still lack nothing (v 35).

When the disciples had depended on God to provide for their needs, those needs were met through generous people. However, the situation had changed. Jesus here instructed His disciples to take a money bag, a knapsack, and a sword on their journeys in order to be prepared for the rejection that was to come.

The Galileans generally travelled with swords. Christ wore none himself, but he was not against his disciples’ wearing them.

Jesus is saying: “I am on the point of leaving you, and when I am gone, you must use common sense means for provision and protection.” Such practical considerations were not needed before, but were needed now.
b. The disciples had been sent out to do ministry without Jesus before (Luk 10:1-17), but then they were received with goodwill and hospitality. Now they are facing a hostile world without Jesus, and must be prepared.
c. It is enough means enough of this kind of talk (Jesus’ firm way of ending the conversation), not two swords will be enough. How could two swords ever be enough against all those who came to arrest Jesus?
i. Jesus’ disciples must be “just as determined and whole-hearted as a fighting man who gives up everything, even his garment, as long as he only possesses a sword to continue the struggle with.” (Geldenhuys)

here are more commentators that agree with a literal interpretation of the verse suggesting that the Disciples, sell their coat and buy a sword:
( I could not fit them all in one post)
Buy a sword (ἀγορασατω μαχαιραν [agorasatō machairan]). This is for defence clearly. The reference is to the special mission in Galilee (Luke 9:16=Mark 6:613=Matt. 9:3511:1). They are to expect persecution and bitter hostility (John 15:1821). Jesus does not mean that his disciples are to repel force by force, but that they are to be ready to defend his cause against attack. Changed conditions bring changed needs.
