I doubt there are more than a few that have heard of The Second Exodus, found in books of the Prophets in the Old Testament.
Act 1:6 When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?
Act 1:7 And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.
Rom 11:25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
Rom 11:26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
Rom 11:27 For this is my covenant unto them, when I shall take away their sins.
Jer 46:27 But fear not thou, O my servant Jacob, and be not dismayed, O Israel: for, behold, I will save thee from afar off, and thy seed from the land of their captivity; and Jacob shall return, and be in rest and at ease, and none shall make him afraid.
Jer 46:28 Fear thou not, O Jacob my servant, saith the LORD: for I am with thee; for I will make a full end of all the nations whither I have driven thee: but I will not make a full end of thee, but correct thee in measure; yet will I not leave thee wholly unpunished.
Rev 11:3 And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
Rev 11:4 These are the two olive trees, and the two candlesticks standing before the God of the earth.
Rev 11:13 And the same hour was there a great earthquake, and the tenth part of the city fell, and in the earthquake were slain of men seven thousand: and the remnant were affrighted, and gave glory to the God of heaven.
God will restore the kingdom to Israel in the future so all Hebrews will be gathered back to Israel.
Israel is blinded in part until salvation is no longer available to the Gentiles which is when they take the mark of the beast.
God will send 2 witnesses to Israel to turn them to the truth for three and one half years and at the end of that time Israel as a nation will be in the truth.
And so all Israel shall be saved.
Israel will be the only operating nation and all Gentile nations will have a full end no more operating government.
Eze 39:21 And I will set my glory among the heathen, and all the heathen shall see my judgment that I have executed, and my hand that I have laid upon them.
Eze 39:22 So the house of Israel shall know that I am the LORD their God from that day and forward.
Eze 39:23 And the heathen shall know that the house of Israel went into captivity for their iniquity: because they trespassed against me, therefore hid I my face from them, and gave them into the hand of their enemies: so fell they all by the sword.
Eze 39:24 According to their uncleanness and according to their transgressions have I done unto them, and hid my face from them.
Rev 10:7 But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.
The mystery of God will be finished which the Gentile nations will know who He is with proof.
Which God will set His glory among the heathen.
And the heathen will know that God was always on Israel's side but they had trouble because God hid His face from them for their iniquity.
Which made the Hebrews look vulnerable during this time which made the heathen say where is your God taking advantage over them for God was not fighting against their enemies like in the past.
They will know the LORD their God from that day forward which they will always be in the truth.
Eze 39:25 Therefore thus saith the Lord GOD; Now will I bring again the captivity of Jacob, and have mercy upon the whole house of Israel, and will be jealous for my holy name;
Eze 39:26 After that they have borne their shame, and all their trespasses whereby they have trespassed against me, when they dwelt safely in their land, and none made them afraid.
Eze 39:27 When I have brought them again from the people, and gathered them out of their enemies' lands, and am sanctified in them in the sight of many nations;
Eze 39:28 Then shall they know that I am the LORD their God, which caused them to be led into captivity among the heathen: but I have gathered them unto their own land, and have left none of them any more there.
Eze 39:29 Neither will I hide my face any more from them: for I have poured out my spirit upon the house of Israel, saith the Lord GOD.
God will bring all the Hebrews back to Israel after they have borne their shame and leave none of them in the nations anymore.
The New Age Christ/antichrist will negotiate peace in the Middle East resulting in a peace treaty which will pave the way for all Hebrews to go to Israel for the Gentile nations will cause it to happen.
Which the antichrist wants them all back on their land but God means it for good towards the Hebrews.
The world will go to a system based on the new age that exalts people on a world wide level and go against all people who oppose them.
God turned Israel to the truth and the world attacks them the battle of Armageddon which Jesus comes back with the saints and defeats the world and saves Israel.
Mat 23:37 O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not!
Mat 23:38 Behold, your house is left unto you desolate.
Mat 23:39 For I say unto you, Ye shall not see me henceforth, till ye shall say, Blessed is he that cometh in the name of the Lord.
The Jews will not see Jesus again until they say blessed is He that comes in the name of the Lord.
Until that time their house is desolate and they are blinded in part.
So it is crucial for Israel as a nation to be in the truth for the plan of salvation to continue.
At the battle of Armageddon they are in the truth and will see Jesus.
Zec 12:1 The burden of the word of the LORD for Israel, saith the LORD, which stretcheth forth the heavens, and layeth the foundation of the earth, and formeth the spirit of man within him.
Zec 12:2 Behold, I will make Jerusalem a cup of trembling unto all the people round about, when they shall be in the siege both against Judah and against Jerusalem.
Zec 12:3 And in that day will I make Jerusalem a burdensome stone for all people: all that burden themselves with it shall be cut in pieces, though all the people of the earth be gathered together against it.
Zec 14:1 Behold, the day of the LORD cometh, and thy spoil shall be divided in the midst of thee.
Zec 14:2 For I will gather all nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city.
Zec 14:3 Then shall the LORD go forth, and fight against those nations, as when he fought in the day of battle.
Zec 14:5 and the LORD my God shall come, and all the saints with thee.
Israel as a nation is in the truth and the world attacks Israel and then God will fight for Israel like He did when Israel was a nation and in the truth.
Because of the peace treaty Jerusalem will be split with the Palestinians and the half that is taken is their side.
They will not be able to take the Hebrews side.
Zec 14:9 And the LORD shall be king over all the earth: in that day shall there be one LORD, and his name one.
Zec 14:16 And it shall come to pass, that every one that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles.
Eze 39:1 Therefore, thou son of man, prophesy against Gog, and say, Thus saith the Lord GOD; Behold, I am against thee, O Gog, the chief prince of Meshech and Tubal:
Eze 39:2 And I will turn thee back, and leave but the sixth part of thee, and will cause thee to come up from the north parts, and will bring thee upon the mountains of Israel.
Jesus will be King of the earth and the heathen will not acknowledge any god or religious figure but Him.
Jesus will rule over one sixth of the world that God spared.
Mat 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Mat 5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Isa 65:17 For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
Rev 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
Jesus came to fulfill the law which includes the offices of Israel.
But He has not fulfilled the role of King for He came as a humble servant and it must be done on earth.
So Israel as a nation has to be restored so there has to be a second Exodus.
When Jesus fulfills the role of King on earth ruling over the heathen this heaven and earth will pass away.
And there will be a new heaven and earth where sin has never been and sin will never be.
And the saints and angels will remember nothing prior to that and will not come to mind.
