The following citations taken from a book on the subject of  Messiah, by Rabbi Nachman of Breslov, offers interesting ideas regarding the relationship between Messiah, "fear of God," the Torah and the "River of Eden" (which appears at the end of the book of Revelation):

Maschiach's duty is to reveal God's greatness which will manifest itself in kindness, good health and blessings. This denotes a total negation of sin and wrongdoing. "When evil is done away with, there will also be no more anger." (Sifri 13:18) It is for this reason that Maschiach will "breathe the fear of God." For he will elevate the idea of fear from the fear of punishment to an exalted level of awe ... the fear of God that will be prevalent in the days of Maschiach ... will be the awe and respect that is befitting true royalty and leadership. The awe of God that will be widespread then will automatically lead people away from evil and towards God. This will eliminate sin and lead to ever greater revelatins of kindness. Maschiach will be a judge -- the ultimate judge -- and will rid the world of suffering. Fear will then be elevated to the awe of God, i.e., respect for God and What He is ...

... Maschiach will "breathe the awe of God." Using prayer as his main weapon ... his "breathing" will have a very positive effect upon mankind. The verse, "And he will breathe the fear of God," in Hebrew is, "Vaharicho b'Yirat HaShem." Our sages teach that B'YiRAT (fear) is the gemmatria of 613. Thus the breath that Maschiach will breathe will emanate from the Torah and its 613 mitzvot. This is (Genesis 1:2) "The Spirit of God (that) hovered over the waters." The spirit is Maschiach and the waters are the Torah. Maschiach's spirit is embedded in the Torah and he will draw his breath, the awe of God, from it ...

Maschiach's job is to bring everyone back to God, even the worst sinner. ... "Proper rebuke thus strengthens the soul by The rectification for one who has sinned and weakened his soul is the 'Voice of Rebuke'." ...

"There is a garden where fragrant smells and fear of God bloom. For (Genesis 2:10), 'The river flows from Eden and waters the Garden...' 'River' represents the Voice of Rebuke as in (Psalms 93:3), 'The rivers have lifted their voice.' This 'voice' which waters the garden (the sweet smells) stems from Eden, the source of the 'Song of the Future'." ...

We see then that the Voice of Rebuke is rooted in Eden, which corresponds to Keter, the source of Maschiach's vitality. ... Maschiach will posess this "Voice of Rebuke" because MaShIaCh is like MaSIaCh, "one who speaks." Since Mashiach is bound together with all souls through his sense of smell (i.e., "the nose"), he will be able to rebuke everyone properly, to arose awe within them and draw them closer to God. His voice will be the flowing "River" from Eden, from which emanate aromatic fragrances, so that everyone will be drawn to the "savory smell" of Mashiach. ¹

The Zohar offers the following regarding the "fear of God" being the "gate to heaven":

Soncino Zohar, Bereshith, 7b - IN THE BEGINNING. R. Hiya opened his discourse thus: The beginning of wisdom is the fear of the Lord; A good understanding have all they that do hereafter. His praise endureth for ever (Ps. CXI, 10). He said: ‘Instead of “the beginning of wisdom” it would be more appropriate to say “the end of wisdom is the fear of the Lord”, since the fear of the Lord is the final object of wisdom. The Psalmist, however, speaks of the highest order of wisdom, which can only be reached through the gate of the fear of God. This is implied in he verse “Open to me the gates of righteousness.... This is the gate of the Lord...” (Psalm 118:19-20). Assuredly, without entering through that gate one will never gain access to the most high King. Imagine a king greatly exalted who screens himself from the common view behind gate upon gate, and at the end, one special gate, locked and barred. Saith the king: He who wishes to enter into my presence must first of all pass through that gate. So here the first gate to super-Wisdom is the fear of God; and this is what is meant by reshith (beginning). The letter Beth (=2) indicates two things joined together, namely two points, one shrouded in mystery and one capable of being revealed; and as they are inseparable they therefore are both joined in the single term reshith (beginning), i.e. they are one and not two, and he who takes away the one takes away the other as well. For He and His name are one, as it is written “That they may know that thou and thy name of Lord art alone” (Psalm 83:19). Why is this first gate called “the fear of the Lord”? Because it is the tree of good and evil. If a man deserves well it is good, and if he deserves ill it is evil.

The "positive aspect" of the Lamb on Mount Zion is balanced by the coming judgment upon the nations. The term "Esau" is used throughout Hebraic writings to describe the nations in the days leading up to the coming of Messiah.

The following text indicates that Jacob's words to Esau, about meeting him at "Mount Seir" were actually prophetic:

The relationship between Israel (i.e., Jacob) and the nations (i.e., Esau) is presented in an enlighening way in the following text. Commenting on Genesis 25:28 ("For Isaac loved Esau because he had a taste for game."), the kabbalistic classic, Sha'are Oreh ("Gates of Light"), depicts Isaac as being "pleased" with Esau, but only because Esau is seen prophetically as being an antagonist that will drive many from Israel back to God and keep them from going to hell:

Could it possibly be that Isaac, our father, for whom the SHeCHINaH never parted for a moment, could love someone as completely wicked as Esau? How is that possible? Rather, this verse speaks of a great essential meaning of the Torah. Know that Isaac, our father, peace be with him, could envision the future and he saw that the children of Jacob would sin and enrage YHVH, may He be blessed, and the judgment of Hell would be their inheritence. When Isaac saw that Israel was in the exile of Esau, he was glad, and he said: "Exile atones for sin." And he said, "Yes, I love the tribulations of Esau, so that they should bring liability to Israel and their harsh judgment shall be finished in the harsh exile of this world," hence the verse, "For Isaac loved Esau because he had the game trapped in his mouth. What does it mean, "the game was trapped in his mouth?" He saw that the children of Jacob would be trapped by the judgments of Hell. He saw this and was saddened. When he saw the exile of Edom (Rome/Esau), however, and he saw the game of Hell trapped in the mouth of Esau, He was happy, and said, "Exile atones for sin." ... Isaac therefore, loved Esau, because he was the agent for arranging that Jacob's sons would not fall into hell. ²

This is another kabbalistic reference to the worlds of Creation; Beriah (heaven), Assiyah (earth), Yetzirah (sea) and avenues of Torah enlightenment ("springs of water") that sustain them all.

The repetition of, "... is fallen, is fallen," indicates the defeat of Babylon (first) in the spiritual realm, then in the physical.

Soncino Zohar, Bereshith, 86a - When God executes judgement on a people, He does so both below and above.

The following Midrash gives some examples of this:

Midrash Rabbah, The Song of Songs VIII:19 - The Holy One, blessed be He, does not punish a nation on earth till He has cast down its guardian angel from heaven. This is borne out by five Scriptural verses. One, the verse, And it shall come to pass in that day, that the Lord will punish the host of the high heaven on high-that first, and then-and the kings of the earth upon the earth (Isaiah 24:21). The second is: How art thou fallen from heaven, O day-star, son of the morning! after which we read, How art thou cut down to the ground (ib. 14:12). The third is: For My sword hath drunk its fill in heaven; and then, Behold, it shall come down upon Edom (ib. 34:5). The fourth: To bind their kings with chains, and then, and their nobles with fetters of iron (Psalm. 149:8), explaining which R. Tanhuma said: ' To bind their kings with chains’: this refers to the heavenly princes. ‘And thegr nobles with fetters of iron’: this refers to the earthly rulers. The fifth is: To execute upon them the judgment written, and then, He is the glory of all His saints, hallelujah (ib. 149:9)

Interestingly, the principle of first defeating the spiritual power behind the physical goes both ways. In this passage from the Zohar, the guardian angels of the nations conspire to first attack the God of Israel, before going after His people:

Soncino Zohar, Shemoth, 58b - IN THE GREATNESS OF THINE EXCELLENCY (lit. uplifting) THOU OVERTHROWEST THEM THAT RISE UP AGAINST THEE. R. Hezekiah found here the same idea as in the verse: “Why standest thou afar off, O Lord? Why hidest thou thyself in time of trouble?” (Ps. x, 1). ‘The sins of mankind,’ he said, ‘cause the Holy One to ascend higher and higher, and then men cry bitterly but without avail, because the Holy One has departed from the world, and they are unable to return to Him.’ R. Isaac, however, applied these words to the time when the Holy One will adorn Himself with majesty in face of the nations who will gather against Him, of whom it says: “The kings of the earth set themselves, and the rulers take counsel together against the Lord and against his anointed” (Psalm 2:2). We are told that the seventy guardians of the nations will at that time gather from all sides with the armies of the whole world and start war against Jerusalem the holy city, and take counsel together against the Holy One. They will say: “Let us rise first against the Patron, and then against His people and against His sanctuary!” Then “He that sitteth in the heavens shall laugh; ehe Lord shall have them in derision” (v. 4). He will put on His majesty and shall dash them in pieces.’ R. Abba said, in the name of R. Jesse the Elder-and R. Simeon made the same remark- that the Holy One will bring to life again all those kings who afflicted Israel and Jerusalem: Hadrian, Lupinus, Nebuchadnezzar, Sennacherib, and all the other kings of the nations who have destroyed His house, and set them up again as rulers, and they shall gather many nations, and then He will do vengeance and justice upon them near Jerusalem, as it is written: “And this shall be the plague wherewith the Lord will smite all the people that have fought against Jerusalem” (Zechariah 14:12). On the other hand, here it says: “In the greatness of thy excellency Thou wilt overthrow thine opponents”, which refers to the Messianic times; and so this song has an eternal significance.

It is taught that both Babylon and Israel fall, "never to pick themselves up again." However in the case of Israel, God Himself will lift her up:

Soncino Zohar, Vayikra, 6a,b - R. Aha was once walking in company with R. Judah. As they were going along, R. Judah said: ‘We have learnt that the “Virgin of Israel” is blessed from seven sources; yet the Scripture says, in reference to her, “And do thou, O son of man, raise a lament over the virgin of Israel”, [Tr. note: This verse is not found in our text. Apparently the Zohar meant it for a paraphrase of Ezekiel 19:1, “And do thou raise a lamentation over the princes of Israel”.] and what is even worse, “The virgin of Israel is fallen, she shall no more rise” (Amos v, 2). It is true that this last verse has been explained by all the Companions as a message of comfort. [Tr. note: In T. B. Berachoth, the verse is explained thus: “She has fallen, but shall no more; rise, O virgin of Israel.’,] This, however, can hardly be accepted, as the prophet himself calls it a lamentation (v. I).’ Said R. Aha: ‘I, too, have been perplexed with the same difficulty. I once came before R. Simeon looking very troubled. He said to me: “Your face shows that there is something on your mind.” I said: “Truly my mind is as sad as my face.” He said to me: “Tell me what it is.” I said: “It is written, ‘The virgin of Israel is fallen, she shall no more rise’. If a man is angry with his wife and she leaves him, shall she never return? If so, alas for the children who have been sent away with her!” He said to me: “Are you not content with what the Companions have said?” I replied: “I have heard their explanation, that it is really a message of comfort, but it does not satisfy me.” He said: “What the Companions have said is quite right as far as it goes, but there is more to be said. Alas for the generation when the shepherds are gone and the sheep stray without knowing whither they are going! Truly this verse requires understanding, but it is all plain to those who can interpret the Torah fittingly. See now. In all the other exiles of Israel a term was set, at the end of which Israel returned to God and the Virgin of Israel came back to her place. But this last exile is not so, for she shall not return as on previous occasions, as is proved by this verse which says, ‘The virgin of Israel is fallen, she shall rise no more.’ Note that it is not written, ‘I shall not raise her any more’. Imagine a king who was wroth with his queen and banished her from his palace for a certain time. When that time arrived she at once returned to the king. So it happened several times. Finally, however, she was banished from the king's palace for a very long time. Said the king: ‘This time is not like the other times when she came back to me. This time I shall go with all my followers to find her.’ When he came to her he found her in the dust. Seeing her thus humiliated and yearning once more for her, the king took her by the hand, raised her up, and brought her to his palace, and swore to her that he would never part from her again. So the Community of Israel, on all previous occasions in which she was in exile, when the appointed time came, used to return of herself to the King; but in this exile the Holy One, blessed be He, will himself take her by the hand and raise her and comfort her and restore her to his palace. So it is written: ‘In that day I will raise up the tabernacle of David that is fallen’ (Amos IX, 11), the ‘tabernacle of David’ being identical with the ‘Virgin of Israel’.” Said R. Judah: ‘Truly thou hast comforted and satisfied me, and this is the truth of the matter. And it reminds me of something similar which I had forgotten, of a saying of R. Jose, that the Holy One, blessed be He, will one day make proclamation concerning the Community of Israel, saying “Shake thyself from the dust, arise, sit thee down, Jerusalem” (Isaiah 52:2), like a man taking his neighbour by the hand and saying, Pull yourself together, rise.’ Said R. Aha to him: ‘All the prophets use similar language. Thus it is written, “Arise, shine forth, for thy light is come”, meaning that the King is here to be reconciled with her. And again, “Behold thy king cometh unto thee” (Zechariah 9:9): He shall come to thee to comfort thee, to raise thee, to repay thee all, to take thee into His palace and to espouse thee for evermore, as it is written: “And I shall betroth thee for ever” (Hosea 2:19).’

The coming of Messiah and the destruction of Babylon results in the total and final transference of "Esau's blessing" to Jacob, as explained in the following text:

Soncino Zohar, Bereshith, Section 1, Page 143b - Observe that as soon as Jacob and Esau commenced to avail themselves of their blessings, the former possessed himself of his portion on high, and the latter of his portion here below. R. Jose the son of R. Simeon, the son of Laqunia, once said to R. Eleazar: ‘Have you ever heard from your father how it comes about that the blessings given by Isaac to Jacob have not been fulfilled, while those given to Esau have all been fulfilled in their entirety?’ R. Eleazar replied: ‘All the blessings are to be fulfilled, including other blessings with which God blessed Jacob. For the time being, however, Jacob took his portion above and Esau here below. But in aftertime, when the Messiah will arise, Jacob will take both above and below and Esau will lose all, being left with no portion of inheritance or remembrance whatever. So Scripture says: “And the house of Jacob shall be a fire, and the house of Joseph a flame, and the house of Esau for stubble, etc.” (Obadiah 1:18), so that Esau will perish entirely, whilst Jacob will inherit both worlds, this world and the world to come. Of that time it is further written: “And saviours shall come up on Mount Zion to judge the mount of Esau; and the kingdom shall be the Lord's” (Ibid. 1:21), that is to say, the kingdom which Esau has taken in this world shall revert to God. For although God rules both above and below, yet for the time being He has given to all the peoples each a portion and an inheritance in this world; but at that time He will take away dominion from all of them, so that all will be His, as it is written, “And the kingdom shall be the Lord's”. It will be the Lord's alone, as it is further written, “And the Lord shall be king over all the earth; in that day shall the Lord be One, and his name One” (Zechariah 14:9).’

Again citing Sha'are Oreh, the concept of the "two females" being united is expressed as follows:

Binah and Malkut face one another. And from the attribute Binah will come all blessings to the attribute Malkut, the essence of which is, "And a river went out from Eden ..." (Genesis 2:10). This is the essence of Binah, which goes out from the place of Keter, through the hands of Chokmah ... For Binah is referred to as the channels of the river. "... to water the garden ..." (Genesis 2:10). This is the sphere Malkut, who receives much everflow and blessing which emanates through the sphere Binah. ⁴

The following Midrash links the nations "drinking from a cup of reeling" to the River of Eden:

Midrash Rabbah, Leviticus 13:5 - R. Samuel b. Nahman said: All the prophets foresaw the empires engaged in their [subsequent] activities. This is alluded to in what is written, And a river went out of Eden to water the garden; and from thence it parted and became four heads (Genesis 2:10). R. Tanhuma, and some say R. Menahema, in the name of R. Joshua b. Levi, said: The Holy One, blessed be He, will, in the Time to Come, cause the heathen nations to drink the cup of reeling. This is indicated by what is written, ’ And a river went out of Eden (‘eden),’ i.e. from the place whence judgment (din) is to go forth.

(See comments to verse 12 below, regarding the relationship between; the River of Eden, God's judgment and the righteous (tzaddikim).

God, through the prophet Jeremiah, tells the nations who do not wish to accept what is coming to them, that if He is bringing judgment on Jerusalem (the city called by his name) He will certainly bring it upon them. This could be an allusion to the dual judgment of verses 14-20 below which may be decribing judgment against Israel and then the nations (note the reference to the "roaring voice" from above and the "grapes" being trampled):

Jeremiah Chapter 25:15-31 - For thus says the Lord God of Israel to me; Take the wine cup of this fury from my hand, and make all the nations, to whom I send you, drink it. And they shall drink, and stagger, and be crazed, because of the sword that I will send among them. Then I took the cup from the Lord’s hand, and made all the nations drink, to whom the Lord had sent me; Jerusalem, and the cities of Judah, and its kings, and its princes, to make them a desolation and a waste, a thing to be hissed, and a curse; as it is this day; Pharaoh king of Egypt, and his servants, and his princes, and all his people; And all the mixed tribes, and all the kings of the land of Uz, and all the kings of the land of the Philistines, and Ashkelon, and Azzah, and Ekron, and the remnant of Ashdod, Edom, and Moab, and the Ammonites, And all the kings of Tyre, and all the kings of Sidon, and the kings of the islands which are beyond the sea, Dedan, and Tema, and Buz, and all who cut the corners of their hair, And all the kings of Arabia, and all the kings of the mixed tribes who dwell in the desert, And all the kings of Zimri, and all the kings of Elam, and all the kings of the Medes, And all the kings of the north, far and near, one with another, and all the kingdoms of the world, which are upon the face of the earth; and the king of Sheshach shall drink after them. Therefore you shall say to them, Thus says the Lord of hosts, the God of Israel; Drink, and be drunk, and vomit, and fall, and rise no more, because of the sword which I will send among you. And it shall be, if they refuse to take the cup from your hand to drink, then shall you say to them, Thus says the Lord of hosts; You shall certainly drink. For, behold, I begin to bring evil to the city which is called by my name, and should you go utterly unpunished? You shall not be unpunished; for I will call for a sword upon all the inhabitants of the earth, says the Lord of hosts. Therefore prophesy against them all these words, and say to them, The Lord shall roar from on high, and utter his voice from his holy habitation; he shall mightily roar upon his habitation; he shall give a shout, as those who trample the grapes, against all the inhabitants of the earth. A noise shall come even to the ends of the earth; for the Lord has a controversy with the nations, he will enter into judgment with all flesh; he will give those who are wicked to the sword, says the Lord.

^13a Then I heard a voice from heaven saying to me, "Write: "Blessed are the dead who die in the Lord from now on."' "Yes," says the Spirit, "that they may rest from their labors,

Here we appear to have a "conversation" between the "bat kol" (voice of heaven) and the "Spirit" (Ruach). We see a similar dialogue in this Midrash:

Midrash Rabbah, Lamentations I:50 - A Bath Kol issued forth and proclaimed, ’A joyful mother of children’ (Psalm 113:9); and the Holy Spirit cried out, FOR THESE THINGS I WEEP.

As is taught in Judaism, when we stand before God, all that accompanies us is our good works -- those actions that contributed to tikkun (rectification) of our own souls and of the world.
