1 Concerning the Ammonites, thus saith the LORD; Hath Israel no sons? hath he no heir? why then doth their king inherit Gad, and his people dwell in his cities? 2 Therefore, behold, the days come, saith the LORD, that I will cause an alarm of war to be heard in Rabbah of the Ammonites; and it shall be a desolate heap, and her daughters shall be burned with fire: then shall Israel be heir unto them that were his heirs, saith the LORD. 3 Howl, O Heshbon, for Ai is spoiled: cry, ye daughters of Rabbah, gird you with sackcloth; lament, and run to and fro by the hedges; for their king shall go into captivity, and his priests and his princes together. 4 Wherefore gloriest thou in the valleys, thy flowing valley, O backsliding daughter? that trusted in her treasures, saying, Who shall come unto me? 5 Behold, I will bring a fear upon thee, saith the Lord GOD of hosts, from all those that be about thee; and ye shall be driven out every man right forth; and none shall gather up him that wandereth. 6 And afterward I will bring again the captivity of the children of Ammon, saith the LORD. 7 Concerning Edom, thus saith the LORD of hosts; Is wisdom no more in Teman? is counsel perished from the prudent? is their wisdom vanished? 8 Flee ye, turn back, dwell deep, O inhabitants of Dedan; for I will bring the calamity of Esau upon him, the time that I will visit him. 9 If grapegatherers come to thee, would they not leave some gleaning grapes? if thieves by night, they will destroy till they have enough. 10 But I have made Esau bare, I have uncovered his secret places, and he shall not be able to hide himself: his seed is spoiled, and his brethren, and his neighbours, and he is not. 11 Leave thy fatherless children, I will preserve them alive; and let thy widows trust in me. 12 For thus saith the LORD; Behold, they whose judgment was not to drink of the cup have assuredly drunken; and art thou he that shall altogether go unpunished? thou shalt not go unpunished, but thou shalt surely drink of it. 13 For I have sworn by myself, saith the LORD, that Bozrah shall become a desolation, a reproach, a waste, and a curse; and all the cities thereof shall be perpetual wastes. 14 I have heard a rumour from the LORD, and an ambassador is sent unto the heathen, saying, Gather ye together, and come against her, and rise up to the battle. 15 For, lo, I will make thee small among the heathen, and despised among men. 16 Thy terribleness hath deceived thee, and the pride of thine heart, O thou that dwellest in the clefts of the rock, that holdest the height of the hill: though thou shouldest make thy nest as high as the eagle, I will bring thee down from thence, saith the LORD. 17 Also Edom shall be a desolation: every one that goeth by it shall be astonished, and shall hiss at all the plagues thereof. 18 As in the overthrow of Sodom and Gomorrah and the neighbour cities thereof, saith the LORD, no man shall abide there, neither shall a son of man dwell in it. 19 Behold, he shall come up like a lion from the swelling of Jordan against the habitation of the strong: but I will suddenly make him run away from her: and who is a chosen man, that I may appoint over her? for who is like me? and who will appoint me the time? and who is that shepherd that will stand before me? 20 Therefore hear the counsel of the LORD, that he hath taken against Edom; and his purposes, that he hath purposed against the inhabitants of Teman: Surely the least of the flock shall draw them out: surely he shall make their habitations desolate with them. 21 The earth is moved at the noise of their fall, at the cry the noise thereof was heard in the Red sea. 22 Behold, he shall come up and fly as the eagle, and spread his wings over Bozrah: and at that day shall the heart of the mighty men of Edom be as the heart of a woman in her pangs. 23 Concerning Damascus. Hamath is confounded, and Arpad: for they have heard evil tidings: they are fainthearted; there is sorrow on the sea; it cannot be quiet. 24 Damascus is waxed feeble, and turneth herself to flee, and fear hath seized on her: anguish and sorrows have taken her, as a woman in travail. 25 How is the city of praise not left, the city of my joy! 26 Therefore her young men shall fall in her streets, and all the men of war shall be cut off in that day, saith the LORD of hosts. 27 And I will kindle a fire in the wall of Damascus, and it shall consume the palaces of Ben-hadad. 28 Concerning Kedar, and concerning the kingdoms of Hazor, which Nebuchadrezzar king of Babylon shall smite, thus saith the LORD; Arise ye, go up to Kedar, and spoil the men of the east. 29 Their tents and their flocks shall they take away: they shall take to themselves their curtains, and all their vessels, and their camels; and they shall cry unto them, Fear is on every side. 30 Flee, get you far off, dwell deep, O ye inhabitants of Hazor, saith the LORD; for Nebuchadrezzar king of Babylon hath taken counsel against you, and hath conceived a purpose against you. 31 Arise, get you up unto the wealthy nation, that dwelleth without care, saith the LORD, which have neither gates nor bars, which dwell alone. 32 And their camels shall be a booty, and the multitude of their cattle a spoil: and I will scatter into all winds them that are in the utmost corners; and I will bring their calamity from all sides thereof, saith the LORD. 33 And Hazor shall be a dwelling for dragons, and a desolation for ever: there shall no man abide there, nor any son of man dwell in it. 34 The word of the LORD that came to Jeremiah the prophet against Elam in the beginning of the reign of Zedekiah king of Judah, saying, 35 Thus saith the LORD of hosts; Behold, I will break the bow of Elam, the chief of their might. 36 And upon Elam will I bring the four winds from the four quarters of heaven, and will scatter them toward all those winds; and there shall be no nation whither the outcasts of Elam shall not come. 37 For I will cause Elam to be dismayed before their enemies, and before them that seek their life: and I will bring evil upon them even my fierce anger, saith the LORD; and I will send the sword after them, till I have consumed them: 38 And I will set my throne in Elam, and will destroy from thence the king and the princes, saith the LORD. 39 But it shall come to pass in the latter days, that I will bring again the captivity of Elam, saith the LORD.
[AD 444] Cyril of Alexandria on Jeremiah 49:10
Jeremiah refers to these angels as a fortification, although Symmachus interprets this [word] as a message, but one could also consider it in the sense of a “siege.” Taking it this way, God calls together many nations for war as a sign against Idumea and the angels are set in motion by him. And, having been set in motion by God for war, they incite others to fight [with them], as Obadiah says. For the surrounding nations were allied with Israel against Idumea. Therefore, turning to the Idumeans, he says, “See I have made you small among the nations and utterly contemptible. You will fall into calamities, ignorant of what is happening to you because you exalted yourself high above your station. Thus it is true that “Idumea will be deserted” and also what follows, which is said in a similar way by Obadiah: “And the house of Esau will be stubble and [Israel] shall descend on him, and there will be no torch bearer in the house of Esau.” This is similar to the adage we find in the profane books, “No torch bearer was spared by them” referring to those who were cut down and utterly destroyed. For the one who held the torch would go out in front of the fighting army to lead them into battle—and there was no one to carry the law against the hand of this enemy [i.e., the angels].

[AD 458] Theodoret of Cyrus on Jeremiah 49:14
He used the phrase “he sent messengers to the nations” to mean “command.” It is also likely that by divine command ministering angels stirred up the enemy. Remember that the divine David also says, “He sent forth on them the wrath of his anger; anger, wrath and distress, a dispatch by means of wicked angels.” He calls them “wicked,” not as such by nature but as communicating punishment as a benefit. We, too, are in the habit of calling the calamities that befall us evil. Likewise an angel wiped out the firstborn of the Egyptians. In the same way, other calamities were sent against Israel when David took a census of the people. There are many other such examples you could find in the divine Scripture.

[AD 420] Jerome on Jeremiah 49:16
“Fir trees are the home of the heron.” The heron is a mighty bird; they say, too, that it overpowers the eagle and feeds on it. It is not like other birds that build their nests and fly to them in the evening; wherever darkness overtakes the heron, there it sleeps. Allegorically, the monk does not have a cell, but wherever he finds one, there, too, he stays. His battle is with the devil, who reigns in this world; like the heron, he prevails over the eagle, the king of the birds, just as it is written: “Though you go as high as the eagle, from there I will bring you down, says the Lord,” for, according to Ezekiel, the eagle is the devil. “The high mountains are for the stags.” This animal kills serpents and eats them; therefore, the mountains are the right habitat for the slayer of the wise serpent, the serpent that, in the garden or paradise, was wiser than all the beasts, the serpent that deceived Eve. “The cliffs are a refuge for rock badgers.” One who is fearful has a rock fastness for his refuge; the rock, moreover, is Christ.

[AD 373] Ephrem the Syrian on Jeremiah 49:39
“It shall come to pass in later days that I will bring back the captives of Elam,” which refers to the time after seventy years of Jewish exile, when Cyrus, after destroying the Chaldean kingdom, would return all captured and enslaved people to their native lands. The divine Paul says, “Whatever was written of old was written for our instruction.” Thus, the Holy Spirit ordered Jeremiah and other prophets to record events of the captivity and of the return of magnificent and great nations in their own time, so that we would have a clear and vivid depiction of our slavery under the burden of Satan, as well as providing us with a picture of the divine household of our Lord who, through his death, bestowed on us life and redemption.Moreover, the Holy Spirit instructs us that a human being should not complain about the truth of God when wicked people experience great calamities. But we always must think about the severe judgment that happened to great nations and listen to the prophet who exhorts us, saying, “Serve the Lord with fear, and rejoice with trembling, so that he will not be angry and you will not perish from his way. For his wrath may soon be kindled.”
