Destroy those who attack Israel?

Nation will rise against nation. It has always been God's method to use the unrighteous to judge the wicked who call themselves by His name. The State of Israel is not innocent, nor performing the will of God, so the nations come against them as prophesied.

"Circumcise yourselves to the LORD And remove the foreskins of your heart, Men of Judah and inhabitants of Jerusalem, Or else My wrath will go forth like fire And burn with none to quench it, Because of the evil of your deeds." Jeremiah 4:4

"Behold, the days are coming," declares the LORD, "that I will punish all who are circumcised and yet uncircumcised." Jeremiah 9:25

But He will not make a complete end of them.

"But I had concern for My holy name, which the house of Israel had profaned among the nations where they went. Therefore say to the house of Israel, 'Thus says the Lord GOD, "It is not for your sake, O house of Israel, that I am about to act, but for My holy name, which you have profaned among the nations where you went. I will vindicate the holiness of My great name which has been profaned among the nations, which you have profaned in their midst. Then the nations will know that I am the LORD," declares the Lord GOD, "when I prove Myself holy among you in their sight." Ezekiel 36

"There you will remember your ways and all your deeds with which you have defiled yourselves; and you will loathe yourselves in your own sight for all the evil things that you have done. "Then you will know that I am the LORD when I have dealt with you for My name's sake, not according to your evil ways or according to your corrupt deeds, O house of Israel," declares the Lord GOD.'" Ez 20

"You have not heard, you have not known. Even from long ago your ear has not been open, Because I knew that you would deal very treacherously; And you have been called a rebel from birth. "For the sake of My name I delay My wrath, And for My praise I restrain it for you, In order not to cut you off. Behold, I have refined you, but not as silver; I have tested you in the furnace of affliction. For My own sake, for My own sake, I will act; For how can My name be profaned? And My glory I will not give to another. Listen to Me, O Jacob, even Israel whom I called; I am He, I am the first, I am also the last." Isaiah 48

And so God will command His people, the true remnant overcomers...

Then I heard another voice from heaven say: “Come out of her, my people, so that you will not share in her sins or contract any of her plagues. For her sins are piled up to heaven, and God has remembered her iniquities. Give back to her as she has done to others; pay her back double for what she has done; mix her a double portion in her own cup."

Notice this verse is a command to His people. "Her" is referring to the Harlot, Babylon who rides the beast on many waters and deceives the nations by her sorcery. Who is the harlot? Answer that and you will have much perspective. This is a subject of it's own. For now let's focus back on Israel.

Look at those who belong to the synagogue of Satan, who claim to be Jews but are liars instead. I will make them come and bow down at your feet, and they will know that I love you. Because you have kept My command to endure with patience, I will also keep you from the hour of testing that is about to come upon the whole world, to test those who dwell on the earth. Rev 3

I know your affliction and your poverty — though you are rich! And I am aware of the slander of those who falsely claim to be Jews, but are in fact a synagogue of Satan. Do not fear what you are about to suffer. Look, the devil is about to throw some of you into prison to test you, and you will suffer tribulation for ten days. Be faithful even unto death, and I will give you the crown of life. Rev 2

In the end the result is...

"And in that day I will set about to destroy all the nations that come against Jerusalem. I will pour out on the house of David and on the inhabitants of Jerusalem, the Spirit of grace and of supplication, so that they will look on Me whom they have pierced; and they will mourn for Him, as one mourns for an only son, and they will weep bitterly over Him like the bitter weeping over a firstborn. In that day there will be great mourning in Jerusalem, like the mourning of Hadadrimmon in the plain of Megiddo." Zech 12

"For My eyes are on all their ways; they are not hidden from My face, nor is their iniquity concealed from My eyes. I will first doubly repay their iniquity and their sin, because they have polluted My land; they have filled My inheritance with the carcasses of their detestable idols and with their abominations. O LORD, my strength and my stronghold, And my refuge in the day of distress, To You the nations will come From the ends of the earth and say, "Our fathers have inherited nothing but falsehood, Futility and things of no profit." Jeremiah 16

It is not that we should have rote support for Israel because Scripture tells us not to come against them but to discern the signs of the times and act accordingly. To do this we must bathe in Scripture, remain in prayer and be filld always with the leading of the Spirit. After all...

Now Hagar stands for Mount Sinai in Arabia and corresponds to the present-day Jerusalem, because she is in slavery with her children. But the Jerusalem above is free, and she is our mother. Galatians 4

and

For neither circumcision nor uncircumcision means anything. What counts is a new creation. Peace and mercy to all who walk by this rule, even to the Israel of God. Galatian 6

Then I saw a new heaven and a new earth, for the first heaven and earth had passed away, and the sea was no more. I saw the holy city, the new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from the throne saying: “Behold, the dwelling place of God is with man, and He will live with them. They will be His people, and God Himself will be with them as their God. Rev 21

Christ is the second Adam, and His bride is formed from a remnant of His body (the church) just as Eve was formed from Adam's rib. Let those who have ears to hear...

See Rev 12:12-14 where the previously unbelieving Jews who become believers are grafted back in to the tree of life to join with the currently believing Jews and "gentile" believers. So "all of Israel will be saved."

A man is not a Jew because he is one outwardly, nor is circumcision only outward and physical. No, a man is a Jew because he is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the written code. Rom 2:29
