1 In that day the LORD with his sore and great and strong sword shall punish leviathan the piercing serpent, even leviathan that crooked serpent; and he shall slay the dragon that is in the sea. 2 In that day sing ye unto her, A vineyard of red wine. 3 I the LORD do keep it; I will water it every moment: lest any hurt it, I will keep it night and day. 4 Fury is not in me: who would set the briers and thorns against me in battle? I would go through them, I would burn them together. 5 Or let him take hold of my strength, that he may make peace with me; and he shall make peace with me. 6 He shall cause them that come of Jacob to take root: Israel shall blossom and bud, and fill the face of the world with fruit. 7 Hath he smitten him, as he smote those that smote him? or is he slain according to the slaughter of them that are slain by him? 8 In measure, when it shooteth forth, thou wilt debate with it: he stayeth his rough wind in the day of the east wind. 9 By this therefore shall the iniquity of Jacob be purged; and this is all the fruit to take away his sin; when he maketh all the stones of the altar as chalkstones that are beaten in sunder, the groves and images shall not stand up. 10 Yet the defenced city shall be desolate, and the habitation forsaken, and left like a wilderness: there shall the calf feed, and there shall he lie down, and consume the branches thereof. 11 When the boughs thereof are withered, they shall be broken off: the women come, and set them on fire: for it is a people of no understanding: therefore he that made them will not have mercy on them, and he that formed them will shew them no favour. 12 And it shall come to pass in that day, that the LORD shall beat off from the channel of the river unto the stream of Egypt, and ye shall be gathered one by one, O ye children of Israel. 13 And it shall come to pass in that day, that the great trumpet shall be blown, and they shall come which were ready to perish in the land of Assyria, and the outcasts in the land of Egypt, and shall worship the LORD in the holy mount at Jerusalem.
[AD 379] Basil of Caesarea on Isaiah 27:1
Let us earnestly endeavor, therefore, to flee every crooked and tortuous act, and let us keep our mind and the judgment of our soul as straight as a rule, in order that the praise of the Lord may be permitted to us since we are upright. In the same way the serpent, which is the author of sin, is called crooked, and the sword of God is drawn against the dragon, the crooked serpent, which makes many twists and turns in its progress.… Therefore one who follows the serpent shows that his life is crooked, uneven and filled with contrarieties; but one who follows after the Lord makes his paths straight and his footprints right.

[AD 420] Jerome on Isaiah 27:1
(Chapter 27 - Verse 1) On that day the Lord will visit with His hard, great, and strong sword Leviathan, the twisted serpent, and Leviathan, the fleeing serpent, and He will slay the sea monster that is in the sea. LXX: On that day God will bring forth His holy, great, and strong sword against the fleeing dragon, against the twisted dragon, and He will slay the dragon that is in the sea. The Hebrews understand the devil, that is, the accuser, whose Greek name is Satan (), to be called in Hebrew Satan (), which means adversary. And in Zachariah it is said: Satan stood at his right hand, to resist him (Zech. III, 1). And he is also called Belial (), that is, apostate, transgressor, and without yoke. And so the Apostle says: What fellowship hath Christ with Belial? (2 Cor. VI, 15). And wherever the LXX translate the sons of iniquity, in the Hebrew it is written, sons of Belial. And that which is sung in the psalm about the mystery of the Savior: The son of iniquity shall not afflict him (Ps. LXXXVIII, 23), in the Hebrew it is said, son of Belial. And it is called by other names, as it is written in another psalm: You shall walk upon the asp and the basilisk, and you shall trample the lion and the dragon (Psalm 90, 13). This dragon is properly called Leviathan in the Hebrew language. It is the great sea monster, of which, that it must be caught by Christ, is mystically narrated in the book of Job: He who will capture the great sea monster (Job 40, 20); for there, Leviathan is also used instead of sea monster; and again: You will draw out the dragon with a hook, you will encircle his jaws with a bridle; And immediately: This is the beginning of the creation of the Lord, which was made to be played with by his angels. And in the psalm: This great and spacious sea: there are creatures without number: small creatures with the great ones. This dragon that you formed to mock him (Ps. CIII, 25, 26). John also writes about this in the Apocalypse: A battle took place in heaven: Michael and his angels fought with the dragon, and the dragon fought and his angels, and they did not prevail, nor was a place found for them in heaven (Apoc. XII, 7 et seqq.). And the great dragon was thrown down, the old serpent, who is called the devil and Satan, who deceives the whole world; he was thrown down to the earth, and his angels were thrown down with him. And I heard a loud voice in heaven, saying, 'Now the salvation and the power and the kingdom of our God and the authority of his Christ have come, for the accuser of our brothers has been thrown down, who accuses them day and night before our God.' (Revelation 12:9-10). It should be noted that in the psalm and in Job, the dragon is called Leviathan, to mock him by the angels. And so the Apostles receive power, that they may tread upon serpents and scorpions and upon all the might of the enemy (Luke 10). Therefore, from that place where it is written: Behold the Lord will lay waste the earth and make it desolate (Isaiah 24:1); or according to the Septuagint: Behold the Lord will destroy the world and lay it waste, until the present chapter, the judgment against the world at the consummation of the age has been preached, and the final enemy death will be destroyed (1 Corinthians 15): therefore, against the devil the ultimate sentence is that he be attacked with a holy, great, and strong sword, or according to the Hebrew and other interpreters, a harsh sword. For it is not as the Seventy perceived Cadesa, which, if it were, would sound holy; but Casa, which properly means hard. Hence also Saul, the father of Cis, is called hard. And some of our people understand the holy or hard sword to be the Word of God, because of its sense which it endures, of which the Apostle says: 'For the word of God is living and effectual, and more piercing than any two-edged sword' (Hebrews 4:12). And in another place we read about the double-edged sword of the Savior coming forth from his mouth (Apoc. XIX). But at the end of the world, against Leviathan, who is called the most cunning serpent in the beginning of Genesis, the holy and strong sword will be brought forth, which will flee from the one who has never been accustomed to fleeing, not knowing that written: Where can I go from your Spirit? Where can I flee from your presence? (Ps. CXXXVIII, 7)? A certain poet beautifully describes in the Gigantomachia about Enceladus:

Where are you fleeing, Enceladus? Wherever you may go, you will always be under God. But that fleeing serpent Leviathan is called Bari in Hebrew, which the Eagle interpreted as a bolt, Symmachus as a lock, and Theodotion as strong. I think it is called a bolt or a lock because it has locked many in its prison and subjected them to its power, and it does not possess anything straight within itself, and for this reason it is called tortuous, and it cannot imitate the rod of the Lord, of which it is written: A rod of direction, a rod of your kingdom (Psalm 44). Whom the Lord will kill with the breath of his mouth (2 Thess. 2), the former inhabitant of the sea, the false and bitter waves. Those who say that the devil will repent and obtain forgiveness, let them explain to us how they understand this, which is written: And he will kill the dragon who is in the sea, or the whale. For in the second place, in the present chapter, in Hebrew it is not called Leviathan, but Thannin (), which properly means whale. The Hebrews believe that Leviathan dwells under the earth and in the heavens, while the sea monsters dwell in the sea, which is a Jewish fable. And what is said at the end of this chapter is connected by Eusebius to the previous chapter, so that the following prophecy is not related to this time. However, the Hebrews and other commentators explain the following, which we are now going to set forth.

[AD 604] Gregory the Dialogist on Isaiah 27:1
For “Leviathan” is interpreted to be “their addition.” Whose “addition,” then, but the “addition” of people? And it is properly styled “their addition,” for since by his evil suggestion he brought into the world the first sin, he never ceases to add to it day by day by prompting to worse things.Or indeed it is in reproach that he is called Leviathan, that is, styled “the addition of men.” For he found them immortal in Paradise, but by promising the divine nature to immortal beings, he as it were pledged himself to add somewhat to them beyond what they were. But while with flattering lips he declared that he would give what they did not have, he robbed them cunningly even of what they had. And hence the prophet describes this same Leviathan in these words, “Leviathan, the serpent: even Leviathan that crooked serpent.” For this Leviathan crept near to people with tortuous windings through the false promise of what he would give them; for while he falsely promised things impossible, he really stole away even those which were possible.

[AD 604] Gregory the Dialogist on Isaiah 27:1
For who is described by the designation of the “serpent” but our old enemy, at once slippery and crooked, who for the deceiving of humankind spoke with the mouth of a serpent? Of whom it is said by the prophet, “Leviathan the serpent, the crooked one”; who was for this reason allowed to speak with the mouth of a serpent, that by Leviathan’s vessel humanity might learn what he was that dwelt within. For a serpent is not only crooked but slippery as well; and so because he stood not in the uprightness of truth, he entered into a crooked animal.… He spoke to man by means of a slippery animal because if one does not resist him, he secretly slips into the interior of the heart. Now “the dens” of this serpent were the hearts of wicked people.

[AD 420] Jerome on Isaiah 27:2-3
(Verse 2, 3.) On that day, the vineyard of wine will sing for him. I am the Lord who tends it, and I will suddenly water it, lest anyone harm it. LXX: On that day, her desire will be a good vineyard, that she may be a prince. I am a strong city, a city that is besieged: in vain will I give her drink. For they will be captured at night, but the wall will fall during the day. There is much disagreement between the Hebrew and the LXX edition in this passage, therefore we will discuss each one separately. The vineyard about which Isaiah speaks: The vineyard has become a beloved one in a fertile place, which should be understood, let us learn from the Teacher himself (or, rather, let us say): For the vineyard of the Lord of hosts is the house of Israel (Isaiah 5:1), of which it is sung in the psalm: You have brought the vineyard out of Egypt, etc. (Psalm 80:8). To this vineyard also, through Jeremiah, the most bitter cup is given (Jeremiah 25). For when he had sent him to intoxicate all the nations, and the Prophet had willingly offered himself for this task, he is first ordered to make Jerusalem drunk. Where it says: You have deceived me, O Lord, and I was deceived (Jeremiah 20:7). Therefore, Jerusalem will drink and be made to drink a bitter potion, so that she may learn lamentation and weeping. And the Lord says that He has kept her for a long time and given her a place for repentance, but because she refused to return, she will suddenly be made drunk. For the Scripture says that the Lord has acted in this way day and night, always preserving her with His help. And the same beautiful vineyard is called the Seventy by the LXX, in which there was the Law and the Prophets, the priesthood and the pontificate, and the knowledge of God, as the Scripture says: God is known in Judah, His name is great in Israel (Psalm 75:1). What others think, according to their edition, pertains to the Church, which is nothing more beautiful. And of which it is said: Glorious things are spoken of thee, O city of God (Ps. LXXXVI, 3): which is the mother of her offspring, and says in the Song of Songs: The sons of my mother fought against me (Cant. I, 5). And he speaks: I am a firm city, a city that is besieged. He said that it is beautifully besieged, not conquered. And immediately he connects it with the Synagogue, which has been turned from head to tail: In vain do I impart the drink of my teachings to her, for she will be taken in the darkness of her error. And because it does not receive clear light, its wall collapses during the day, that is, everything that it believed to be help for itself, and there will be no opponent who does not understand that we must grasp power from opposites.

[AD 397] Ambrose of Milan on Isaiah 27:3
It is the soul, too, that says, “I am a strong city, a city besieged.” The city is besieged through Christ, the city is that heavenly Jerusalem, in which there are interpreters of God’s law and men skilled in doctrine in great abundance; through them one seeks the Word of God.

[AD 397] Ambrose of Milan on Isaiah 27:3
Therefore let us flee these evils and elevate our soul to the image and likeness of God. The flight from evils is the likeness of God, and the image of God is gained through the virtues. And so, like a painter, he has painted us with the colors of the virtues. “See, I have painted your walls, Jerusalem.” Let us not wipe away with the brush of neglect the props of the painted walls of our soul. And so “I have painted the walls,” with which we can turn away the enemy. The soul has its walls; from them it stands forth and concerning them it says, “I am a strong city, a city besieged.” By these walls it is guarded, and by them it is protected under siege. And truly the soul is a wall, which stretches forth over the camp. And therefore the bride says in the Song of Solomon, “I am a wall, and my breasts are like towers.” The wall that the Lord painted is good, even as he says: “On my hands I have painted your walls, and you are always in my sight.”

[AD 397] Ambrose of Milan on Isaiah 27:3
You have in Isaiah the speech made by the soul of a just man or of the church: “I am a strong city, I am a city besieged,” defended by Christ and besieged by the devil. But one whom Christ aids ought not to be fearful of a siege. [Such a person] is defended by spiritual grace and is besieged by the perils of this world. Hence also it is said in the Song of Songs, “I am a wall, and my breasts are as a tower.” The wall is the church, and the towers are her priests, who have full power to teach the natural and the moral sciences.

[AD 420] Jerome on Isaiah 27:4-5
(Verse 4, 5.) Indignation is not mine: who will give me a thorn and a thistle in battle? I will march over it: I will set it on fire together. Or rather, shall I hold onto my strength? It will bring me peace, it will bring me peace. LXX: There is nothing that does not seize it. Who will appoint me as a keeper of the straw in the field? Because of this adversary, I have repelled it. Therefore, the Lord has done all that He has planned: I am consumed; its inhabitants will say, we will make peace with it: we will make peace with him. According to the Hebrew, the meaning here is: I who, day and night, have always kept my vineyard, so that the boar from the forest would not destroy it, nor the beasts devour it. Do I not have indignation? And do I not know how to strike the sinner and give to each what he deserves? Where the eagle placed a thorn and a bramble, in Hebrew it is written 'Samir' and 'Saith', which means adamant and places full of thorns. Therefore, he says: Who will teach me to be firm and overcome my mercy, and to proceed fiercely in battle: so that I may walk over the vineyard which I kept, and burn it down which I enclosed with my wall? Or should my courage rather do this, that I postpone anger and save those who are not saved by the authority of the Law, with the mercy of the Gospel? But emphatically, according to the Hebrew reading, it is said: Who will make me hard and cruel, that I may overcome my nature? This is indeed signified in the desert and in thorns: that I may crush and burn it as if in battle, which I have always kept guarded by my diligence. Or should I hold onto my courage, which is undoubtedly Christ, and of which we read: Christ the power of God and the wisdom of God (1 Corinthians 1:24), so that it may itself make peace for me and reconcile the world? According to the Septuagint, here is the meaning: Let us understand it from the perspective of the Church: I am a strong city, a city surrounded by many enemies, to whom I have given in vain the cups of my enemy, the Synagogue. For she will be captured at night, and her wall will fall, and there will be no power of adversaries that will not seize her. Again I will say: What profit is it for me to guard her, which has straw in herself, not grain: which is so uncultivated, that it is full of disgrace and thorns, which I wanted to save? But because she treats me hostilely, I have departed from her. And the Apostles born in me and from me have said: Indeed, it was necessary for you to speak the word of God first, but since you have rejected it and deemed yourselves unworthy of eternal life, behold, we turn to the Gentiles (Acts 13:46). Therefore, the Lord will do what He has threatened, so that all may burn in it surrounded by Roman fire. Or certainly let them burn with vices and sins, lest they be able to extinguish the burning darts of the devil. For all those who commit adultery are like an oven whose hearts are burning. And those who formerly dwelled in it, after they cry out, the city is captured and burned, and they leave it, and reconciling the world (or unclean) to God, they say: Let us make peace to her, let us make peace to Him, which is Christ, always writing in their Letters: Grace be with you and peace from God the Father and Christ Jesus our Lord (1 Corinthians 1:3). Of whom we read in this same Prophet: How beautiful are the feet of those who announce peace (Isaiah 52:7)! Some refer this place to the Churches, because they are indeed guarded by God; but many of them do not bear fruit; and therefore the fervor of a good teacher should succeed, so that they may proclaim and confess their error, and afterwards make peace with God, who are truly called the children of Jacob.

[AD 420] Jerome on Isaiah 27:6
(Verse 6) Those who come out from the root of Jacob will flourish and grow Israel: and they will fill the face of the world with their offspring. LXX: The sons of Jacob who come: Israel will flourish and bloom, and its fruits will fill the earth. After the Apostles, preaching the Gospel in the whole world, have said: We will make peace for Christ, peace will be made for you, those who come from the seed of Jacob and have reached the Apostolic dignity will be called sons of Jacob. Then Israel will sprout and flourish, seeing that the teachings of its children have filled the entire world, and have brought forth abundant fruits that it had not brought while remaining in Judaea.

[AD 420] Jerome on Isaiah 27:7
(Verse 7.) Did he strike him according to the blow of the one striking himself: or as he killed his killers, so was he killed? This place is understood in two ways. Either against Jerusalem, so that he may say that she was not struck by God in the same way that she struck Christ and his Apostles: or against the multitude of the Gentiles, so that the Apostles and apostolic men, despite being persecuted and shedding Christian blood, nevertheless had care for their salvation and reconciled them to God.

[AD 420] Jerome on Isaiah 27:8
(Verse 8) When it has measured out against the measure, you shall judge it. LXX: He will send them out, quarreling and reproaching. According to the Hebrew sense here: As Jerusalem has done, so she will receive, and according to the measure with which she has measured, it will be measured to her in return. And then she will receive a full measure, when the time of judgment comes and God has rejected her. According to the LXX, it depends on what was said earlier. For Israel will not be struck as she has struck, nor will she be killed as she has killed. He argued against the Apostles, and reproached his teachers, and commanded them not to speak in the name of Christ. Therefore the Lord will reject them and cast them out from his flock.

He meditated in his hard spirit during the heat of the day. LXX: Were you not the one who meditated on destroying them with a hard spirit, with a spirit of fury? According to the Hebrew, it is said, 'In the measure that the table is, Jerusalem will receive.' Therefore, God meditated in his hard and vehement spirit, whether speaking against her during the heat of the day, that is, in the time of persecution, when there is a more intense day of indignation and punishment. According to the Septuagint, it is said of Jerusalem, or of Israel: Were you not the one who in your most stubborn and cruel spirit, and in the fury of your blasphemies, desired to kill the Apostles of the Lord and the teachers?

[AD 420] Jerome on Isaiah 27:9
(Verse 9) Therefore, because of this, the iniquity of the house of Jacob will be forgiven, and all this fruit will be removed, so that its sin may be taken away. For they have set up all the stones of the altar like scattered ashes; neither the lights nor the shrines will stand. LXX: Therefore, the iniquity of Jacob will be taken away, and this will be his blessing when I remove his sin, when I set up all the stones of the altars shattered like crushed ash, and their trees and idols will not endure. The reason why they suffer no harm even after the Jews laid hands upon the Lord is that they may obtain forgiveness if they choose to repent, so that the prayer of the Savior may be fulfilled: Father, forgive them; for they know not what they do (Luke 23:34). Therefore, it is said, the iniquity of the house of Jacob will be pardoned, and its sin will be taken away, so that it may deserve the blessing of God, which had been cursed upon it when it said: His blood be upon us, and upon our children (Matthew 27:25). Because through the Apostles, the Gospel will be sown from the stock of Israel throughout the whole world, and idolatry will be destroyed, and altars will be crushed to dust, lights will be cut down, temples will fall, and the knowledge of the one God under the mystery of the Trinity will be proclaimed.

[AD 420] Jerome on Isaiah 27:10
(Verse 10) The fortified city will be deserted; the beautiful city will be abandoned and left like a wilderness. There the calf will graze, and there it will lie down and consume its branches. Their idols will be cut down like groves, and the flock that dwells far away will be left like a deserted flock, and it will be a long time in the pasture, and there the flocks will rest, and after a long time there will be no green in it, for it is dried up. Jerusalem, once a strong and fortified city, because it did not receive its masters but said: Come, let us kill him, for this is the heir and our inheritance (Matthew 21:38), will be deserted. And that which was once beautiful, of which it is said in Ezekiel: You ate fine flour, honey, and oil, and you became exceedingly beautiful (Ezek. 16:13), and in which dwells He of whom it is written: You are fairer than the sons of men (Ps. 45:3), will be left and abandoned like a desert, as the Lord says to the Apostles: Arise, let us go from here (John 14:31). There the calf, the Roman army, will graze, of which it is also said in another place under the name of boar: The boar from the forest will ravage it, and the singular wild beast has grazed on it (Ps. 80:14). And there he will lie down and consume its branches under the metaphor of a vine and its shoots, so that nothing green remains in it, nothing of the branches, but the enemy consumes everything. According to the Septuagint, because they did not receive a good shepherd: therefore they will be like a forsaken flock, and will be open to the bites of beasts; and nothing green will remain in them, because drought will possess everything.

[AD 220] Tertullian on Isaiah 27:11
The women, returning from the sepulcher and from this vision of the angels, were foreseen by Isaiah, when he says, “Come, you women, who return from the vision,” that is, “come” to report the resurrection of the Lord. It was well, however, that the unbelief of the disciples was so persistent, in order that to the last we might consistently maintain that Jesus revealed himself to the disciples as none other than the Christ of the prophets.

[AD 411] Tyrannius Rufinus on Isaiah 27:11
That the women were to see his resurrection, while the scribes and Pharisees and the people disbelieved, this also Isaiah foretold in these words, “You women, who come from beholding, come: for it is a people that has no understanding.”

[AD 420] Jerome on Isaiah 27:11
(Verse 11) In the dryness of its harvest, women who come and teach her will be crushed. For the people are not wise; therefore, the one who made them will not show them mercy, and the one who formed them will not spare them. LXX: Women coming from the spectacle, come: for the people do not have understanding; therefore, the one who made them will not show them mercy, and the one who formed them will not spare them. This is what is said, 'In the dryness of its harvest, they will be crushed,' for which it is interpreted by the Seventy, there will be nothing green in it because it has withered, according to the Hebrew, it is joined to the following; according to the LXX, it is joined to the previous meaning. Let us therefore speak first according to the Hebrew. When the time of drought and harvest of Jerusalem comes, and to speak more clearly, the time of desolation will come, a multitude of synagogues from all over the world will come together to lament for Jerusalem and to console its evils. Whether he speaks openly about women, who, with their breasts exposed, strike their bleeding arms, and the prophecy of the Lord will be fulfilled: Daughters of Jerusalem, do not weep for me, but weep for yourselves and for your children (Luke 23:28). And a great unhappiness of the people is to learn the songs of lamentation from women; just as the people of Israel were rebuked when, in the book of Judges (Judges 4), the Lord brought salvation through the hand of the woman Deborah, and during the nearby captivity, when the men were silent, the woman Holda prophesied (2 Kings 22). Therefore, the women will be worn out by a long journey, weakened by frailty, hunger, and filth, and they will teach the pitiful people, because they are not a wise people, nor have they understood their Creator, who, neglected and despised by them, will not show mercy to their deeds, and will not spare his creation. According to the LXX, it is said of Mary Magdalene, and the other Mary, and the other women, who first saw the Lord rising, and held his feet, and deserved to hear from him: Do not be afraid: Go, tell my brothers to go to Galilee, and there they will see me (Matt. XXVIII, 10). Concerning these women, long before they were born, the prophetic word foretells and calls them from the sight of the Lord's Passion and Resurrection, to preach the Gospel and, according to the Hebrew, to teach Jerusalem or the land of Israel, that he is the Lord and God. For at that time the people of Israel did not have wisdom, when the Lord suffered, and the prophetic prophecy was fulfilled: Save me, O Lord, for the holy one has failed (Psalm 11:1). And: They have all gone astray, they have become useless together, there is no one who does good, not even one (Psalm 13:4), the women are called from the show, so that they may announce to the Apostles what they themselves saw. But Israel, of whom it was said (above, 1:3): Israel did not know me, and my people did not understand, provoked their most merciful Creator and Maker to bitterness, so that he would not show them any mercy. These things are indeed said piously; but how they agree with the others, and how they are adapted to the times of the consummation of the world, is a difficult interpretation.

[AD 420] Jerome on Isaiah 27:12
(Verse 12) And it shall be on that day, the Lord shall strike from the channel of the river to the torrent of Egypt. LXX: And it shall be on that day, the Lord shall shut off from the channel of the river to Rhinocorura. If it had not joined together, on that day, through which we are taught, the things that are to be connected with the things that were said earlier, we could have explained it as the proper sense of this chapter; but now all things must be referred back to the earlier ones. For the fortified city shall be desolate, and the beautiful city shall be forsaken like a desert, and there the calf shall lie down, and it shall devour the branches of the vine, and all things shall become dry, because there is no people who have understanding, and because of their foolishness, they have not obtained any mercy from their Creator. Therefore, the Lord will strike or close off from the channel or stream of the river to the torrent of Egypt, so that in all of Judaea, which was once the promised land, no teaching may be found, no knowledge of the Scriptures, of which the Apostle speaks: In order that we may not pay attention to Jewish myths and commandments of men who turn away from the truth (Titus 1:14); and again: For there are many who are insubordinate, empty talkers, and deceivers, especially those of the circumcision (Ibid., 10). But the riverbed, or the stream of the river, next to the Euphrates, we can call it, as it is written in the seventy-first psalm: He shall have dominion also from sea to sea, and from the river unto the ends of the earth (Psalm 71:8). Others think it is the Jordan. And it should be noted that in the borders of Judea, it is called a river; in the borders of Egypt, a torrent, which has turbid waters and is not permanent. Instead of the torrent of Egypt, the seventy translators translated it as Rhinocorura, which is a town on the border of Egypt and Palestine, expressing not so much the words of the Scriptures as the meaning of the words. But what we said, he will strike, for which the LXX translated συμφράξει as concludet: Aquila and Theodotion interpreted as ῥαβδήσει, which can be understood as either he will strike with a rod or he will count the number of his flock with a rod, so that it is not taken in a bad but in a good sense.

And you shall be gathered one by one, O sons of Israel. LXX: But you, gather together one by one, O sons of Israel. O sons of Israel, for whom Symmachus has interpreted, the house of Israel: striking your enemies from the river stream, even to the river of Egypt, that is, from the Euphrates to the Nile, you yourselves shall be gathered to the faith of the Lord one by one, because the crowd of Jews did not believe, by which it signifies that only a few of the Jews will believe in the Savior Lord. Certainly, O Apostles and apostolic men, when the multitude of Jews did not believe, you, from the whole world, whom you were able, bring back like sick sheep to the folds of the Lord, and gather them with the people of the nations, so that what the Apostle Paul and Barnabas speak to the Jews may be fulfilled: For it was necessary for the word of God to be announced to you first; but since you judged yourselves unworthy of salvation, behold, we turn to the Gentiles (Acts 13:46).

[AD 420] Jerome on Isaiah 27:13
(Verse 13) And it shall be in that day: the great trumpet shall sound, and those who were lost from the land of Assyria and those who were cast out into the land of Egypt shall come, and they shall worship the Lord on the holy mountain in Jerusalem. LXX: And it shall be in that day, a great trumpet shall sound; and those who perished in the region of Assyria and those who perished in Egypt shall come; and they shall worship the Lord on the holy mountain in Jerusalem. In this place, the Jews make empty vows to themselves, that at the end of the world, when their Antichrist, as it is said, shall come, the dispersed people from Assyria and the land of Egypt shall gather together and come to Jerusalem, and having built the temple, worship the Lord their God. That which cannot stand completely according to the letter. For it does not only refer to the Assyrians and Egyptians, but to the whole world, which will believe in Christ. Therefore, this signifies that in the last trumpet, according to the Apostle Paul (1 Cor. XV), all those who perished in Assyria and Egypt will come to the Lord. He did not say all the children of Israel, but all those who perished, indicating the multitude of the Gentiles, who, bound by idolatry, magic, and the arts of philosophy, will come to the faith of Christ and worship Him in the Church. The great trumpet can be understood as the Gospel message, of which we also read in the same Prophet: Ascend to the high mountain, you who bring good news to Zion; lift up your voice with strength, you who bring good news to Jerusalem (Isaiah 40:9). Therefore, that mountain is holy and that Jerusalem is the one of which we have often spoken: You have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to myriads of angels, and to the assembly of the firstborn who are enrolled in heaven (Hebrews 12:22). Up to this point, we have spoken about the end of the world starting from the place where we began: Behold, the Lord will scatter the earth and make it bare (Above, XXIV, 1), which is contained in the present volume. Now, with the help, or rather inspiration, of Christ, let us move on to the ninth, which will have the beginning of another prophecy.
