A prophet says: paradise is under the swords' shadows!

[فداء الرسول]

In The Facile Interpretaion: O who you believe, remember the blessing that Allah gave you (in Madina) at the time of the Combined Forces incursion, when the pagans from outside the Madina united with the Jews and the hypocrites (fom inside the Madina) against you and enclosed you. So, We sent them a strong wind that plucked their tents and destroyed their fortresses, then We sent you angels from heaven you didn't see, that made them scared. Allah knows all what you do, as nothing can hide from Him.
Fourth: after clarifying that there's no suspicion in the prophet's (PBUH) speech, on the contrary, it's one of the prophet's (PBUH) greatest speeches, and proves one of his miracles, as Muslims defeated their enemy when he (PBUH) asked his companions not to wish meeting the enemy, and to be patient when meeting them. Then he (PBUH) invocated to Allah, the Almighty, so He (PBUH) helped them without fighting or blood shedding; Allah, the Almighty, says:" And Allah repelled those who disbelieved, in their rage, not having obtained any good. Allah averted the believers from fighting, and ever is Allah Powerful and Exalted in Might." (The Combined Forces: 25)
After revealing the truth to the objectors, I have a question: Luke's Bible mentions that Jesus, the Lord of devotion as they believe, orders his students to buy swords..why?? Isn't he a good Lord?? Or is he a messenger from Allah??
Luke 22: "36 He said to them, “But now let the one who has a moneybag take it, and likewise a knapsack. And let the one who has no sword sell his cloak and buy one. 37 For I tell you that this Scripture must be fulfilled in me: ‘And he was numbered with the transgressors.’ For what is written about me has its fulfillment.” 38 And they said, “Look, Lord, here are two swords.” And he said to them, “It is enough.” 39 And he came out and went, as was his custom, to the Mount of Olives, and the disciples followed him. 40 And when he came to the place, he said to them, “Pray that you may not enter into temptation.” 41 And he withdrew from them about a stone's throw, and knelt down and prayed, 42 saying, “Father, if you are willing, remove this cup from me. Nevertheless, not my will, but yours, be done.” 43 And there appeared to him an angel from heaven, strengthening him. 44 And being in an agony he prayed more earnestly; and his sweat became like great drops of blood falling down to the ground.[g] 45 And when he rose from prayer, he came to the disciples and found them sleeping for sorrow, 46 and he said to them, “Why are you sleeping? Rise and pray that you may not enter into temptation.”
There's an important question here: Why did Jesus order his students to sell their clothes and buy swords?! Did he mean that paradise is under the swords' shadows, or did he call them for a great battle…?!
The word "sword" is mentioned in the Bible hundreds of times, but it's not mentioned in the Quran even once, don't they have minds to understand?!
I say: The circumstances in this text are very similar to the circumstances of The Combined Forces incursion, as Jesus (PBUH) said these words to his students when they were cordoned by the Jews…
Notice Jesus's (PBUH) words: "Rise and pray that you may not enter into temptation"
I wonder: Isn't these the same words of Muhammad (PBUH)?: "Don't wish meeting the enemy, but if you meet them, be patient and ask Allah to save you from this, meaning that don't wish to enter into temptation…They're both prophets!!
