Oh its in scripture all over the place. And you are the proof that the curse still works like a charm.
"I have not come to bring peace but a sword."
Well, let's take a look at this, shall we? First off, I notice that you chopped the statement off instead of looking at the context. That's your first mistake:
34 Think not that I am come to send peace on earth: I came not to send peace, but a sword.
35 For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law.
36 And a man's foes shall be they of his own household.
Now, anyone with a high school understanding of the English language understands that to mean that following Yeshua is not an easy road at all, and that it brings hardships. For proof of that, simply ask a Muslim what would happen to him if he were to renounce Islam to follow Yeshua.
"From his mouth there went a sharp sword with which to smite the nations"
Oh, dear, I'm afraid you have stepped in it this time. Again with context:
13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
14 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
16 And he hath on his vesture and on his thigh a name written, King Of Kings, And Lord Of Lords.
Who is this? Let's see, His name is The Word of God. Now, where have we heard that name before? Something about being with God and being God in the beginning. Oh, and what's this? He has another name written,
Lord of Lords. Who is that? Let's look to Scripture. From Deuteronomy 10:
17 For the Lord your God is God of gods, and
Lord of lords, a great God, a mighty, and a terrible, which regardeth not persons, nor taketh reward:
Take from my hand this cup of fiery wine and make all the nations to whom I send you drink it. When they have drunk it they will vomit and go mad; such is the sword that I am sending among them"
It helps your credibility when you cite the Scripture you're quoting. Just plopping down some sentences says nothing.
"He who lives by the sword shall die by the sword."
Ah, yes, I recall that part of Yeshua's story. He was telling his disciples to stand back because prophecy was being fulfilled and they should attempt to interfere:
51 And, behold, one of them which were with Jesus stretched out his hand, and drew his sword, and struck a servant of the high priest, and smote off his ear.
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?
54 But how then shall the scriptures be fulfilled, that thus it must be?
That has nothing to do with the sword that Yeshua brought.
Take this cup of wine and drink it, all of you. This is a cup of my blood, the blood of the covenant
Tell us, did the disciples consume actual flesh and blood on that first communion service?
That doesn't have anything to do with the sword that Yeshua brought.
Just art thou, in these thy judgments, thou Holy One who art and wast; for the shed the blood of thy people and of thy prophets and thou hast given them blood to drink"
You've been somewhat amusing with the way you've twisted everything to suit your warped imagination, but that's all. You've not been convincing even a little bit.
