Hoshiyya, I'm wondering, how do we reconcile these two verses?
Matthew 26:52, For all they that take the sword shall perish with the sword.
Luke 20:36, He that hath no sword, let him sell his garment, and buy one.
(If this were a question in logic, what would be the "reasonable" conclusion?)
Throughout, He has ever been a example to them...But now, He will soon be going away... Throughout He has yet ceased from instructing them in how they are to conduct themselves - especially in His absence now, and given the great temptations their coming hardships for His Name in will bring on them...
It is actually rather moving, as all things Him ever are...
Luke 22:
28. Ye are they which have continued with me in my temptations.
29. And I appoint unto you a kingdom, as my Father hath appointed unto me;
31. And the Lord said, Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat:
32. But I have prayed for thee, that thy faith fail not:
and when thou art converted, strengthen thy brethren.
33. And he said unto him, Lord, I am ready to go with thee, both into prison, and to death.
34. And he said, I tell thee, Peter, the [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse] shall not crow this day, before that thou shalt thrice deny that thou knowest me.
35. And he said unto them,
When I sent you without purse, and scrip, and shoes,
lacked ye any thing? And they said, Nothing.
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.
39. And he came out, and went, as he was wont, to the mount of Olives; and his disciples also followed him.
40. And when he was at the place, he said unto them,
Pray that ye enter not into temptation.
41. And he was withdrawn from them about a stone's cast, and kneeled down, and prayed,
42. Saying, Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done.
43. And there appeared an angel unto him from heaven, strengthening him.
44. And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground.
45. And when he rose up from prayer, and was come to his disciples, he found them sleeping for sorrow,
46. And said unto them, Why sleep ye? rise and pray, lest ye enter into temptation.
47. And while he yet spake, behold a multitude, and he that was called Judas, one of the twelve, went before them, and drew near unto Jesus to kiss him.
48. But Jesus said unto him, Judas, betrayest thou the Son of man with a kiss?
49. When they which were about him saw what would follow, they said unto him, Lord,
shall we smite with the sword?
50. And one of them smote the servant of the high priest, and cut off his right ear.
51.
And Jesus answered and said, Suffer ye thus far. And he touched his ear, and healed him.
52. Then Jesus said unto the chief priests, and captains of the temple, and the elders, which were come to him, Be
ye come out, as against a thief, with swords and staves?
53. When I was daily with you in the temple, ye stretched forth no hands against me:
but this is your hour, and the power of darkness.
The swords were a means of allowing them to find out for themselves that their concerns were still somewhat of this world, for while He was yet with them, even in that very moment of His betrayal and the power of darkness; thousands of Angels from Heaven had stood ready at His beck and call; but for the fact that the concerns of this world were not yet His, they had lacked nothing.
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.
53. Thinkest thou that I cannot now pray to my Father, and he shall presently give me more than twelve legions of angels?
John 16:
28. I came forth from the Father, and am come into the world: again, I leave the world, and go to the Father.
29. His disciples said unto him, Lo, now speakest thou plainly, and speakest no proverb.
30. Now are we sure that thou knowest all things, and needest not that any man should ask thee: by this we believe that thou camest forth from God.
31. Jesus answered them, Do ye now believe?
32. Behold, the hour cometh, yea, is now come, that ye shall be scattered, every man to his own, and shall leave me alone: and yet I am not alone, because the Father is with me.
33. These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.
We are to be a prepared people. When Lot and his people were captured, Abraham had no problem rescuing him with force without a Rabbi verification.(Genesis 14:13-16).
