9 Then said I, O my lord, what are these? And the angel that talked with me said unto me, I will shew thee what these be.
[AD 420] Jerome on Zechariah 1:7-11
[Daniel 7:5] "And behold another beast like a bear stood up on one side; and there were three rows in his mouth and in his teeth; and they said to him: 'Arise up and devour flesh in abundance.'" The second beast resembling a bear is the same as that of which we read in the vision of the statue (2:32): "His chest and arms were of silver." In the former case the comparison was based on the hardness of the metal, in this case on the ferocity of the bear. For the Persian kingdom followed a rigorous and frugal manner of life after the manner of the Spartans, and that too to such an extent that they used to use salt and nasturtium-cress in their relish. Let us consult the record of the childhood of Cyrus the Great (i.e., "The Education or Training" of Cyrus). And as for the fact that the bear is said to have "stood up on one side," the Hebrews interpret it by saying that the Persians never perpetrated any cruelty against Israel. Hence they are described in the Prophecy of Zechariah also as white horses (Zechariah 1:7-11). But as for the three rows or ranks that were in his mouth and between his teeth, one authority has interpreted this to mean that allusion was made to the fact that the Persian kingdom was divided up among three princes, just as we read in the sections dealing with Belshazzar and with Darius that there were three princes who were in charge of the one hundred and twenty satraps. But other commentators affirm that these were three kings of the Persians who were subsequent to Cyrus, and yet they fail to mention them by name. But we know that after Cyrus's reign of thirty years his son Cambyses ruled among the Persians, and his brothers the magi, and then Darius, in the second year of whose reign the rebuilding of the Temple was commenced at Jerusalem. The fifth king was Xerxes, the son of Darius; the sixth was Artabanus; the seventh, Artaxerxes who was surnamed Makrokheir, that is Longimanus ("Long-handed"); the eighth, Xerxes; the ninth, Sogdianus; the tenth, Darius surnamed Nothos ("Bastard"); the eleventh, the Artaxerxes called Mnemon, that is, "The Rememberer"; the twelfth, the other Artaxerxes, who himself received the surname of Ochus; the thirteenth, Arses, the son of Ochus; and the fourteenth, Darius the son of Arsamus, who was conquered by Alexander, the king of the Macedonians. How then can we say that these were three kings of the Persians? Of course we could select some who were especially cruel, but we cannot ascertain them on the basis of the historical accounts. Therefore the three rows in the mouth of the Persian kingdom and between its teeth we must take to be the three kingdoms of the Babylonians, the Medes, and the Persians, all of which were reduced to a single realm. And as for the information, "And thus they spake to him: 'Devour flesh in abundance,'" this refers to the time when in the reign of the Ahasuerus whom the Septuagint calls Artaxerxes, the order was given, at the suggestion of Haman the Agagite, that all the Jews be slaughtered on a single day (Esther 3:13). And very properly, instead of saying, "He was devouring them" the account specifies, "Thus they spake unto him..." This shows that the matter was only attempted, and was by no means ever carried out.

[AD 420] Jerome on Zechariah 1:8-13
(Verse 8 and following) I saw during the night: and behold, a man riding on a red horse, and he stood among the myrtle trees that were in the ravine, and behind him there were red, sorrel, and white horses. And I said, 'What are these, my lord?' And the angel who was speaking with me said to me, 'I will show you what these are.' And the man who was standing among the myrtle trees answered and said, 'These are the ones whom the Lord has sent to go throughout the earth.' And they reported to the angel of the Lord who was standing among the myrtle trees, and said, 'We have gone throughout the earth, and behold, all the earth is peaceful and quiet.' And the angel of the Lord answered and said: O Lord of hosts, how long wilt thou not have mercy on Jerusalem, and on the cities of Juda, with which thou hast been angry? This is the seventieth year. And the Lord answered the angel that spoke in me, good words, and comfortable words. LXX: I saw in the night: and behold a man riding upon a red horse, and he stood among the myrtle trees, that were in the bottom: and behind him were horses, red, speckled, and white. And I said: What are these, my Lord? And the angel who spoke with me said: I will show you what these things are. And the man who stood among the mountains answered and said to me: These are the ones whom the Lord has sent to go around the earth. And they answered the angel of the Lord, who stood among the mountains, and said: We have gone around the whole earth, and behold, all the earth is inhabited and at rest. And the angel of the Lord answered and said: O Lord Almighty, how long will you not have mercy on Jerusalem and the cities of Judah, with which you are angry? This is the seventieth year. And the Lord answered the angel who spoke to me, good words and consoling speeches. First, let us discuss the story: I saw, he said, during the night: not during the day, like Moses, who saw God face to face: and Isaiah who spoke: I saw the Lord sitting on a high and exalted throne (Isa. VI, 1): before the people were led into captivity, before Jerusalem was destroyed and the temple; but still, while the people were in the midst of the evils of servitude, he sees what he sees for them in darkness. And behold, a man riding on a red horse. The Hebrews believe this to be the angel Michael, who is the avenger of iniquities and sins of Israel. And the standing among the myrtle trees that were in the depths, they want to understand as the prophets and saints who dwelled among the captive people and were in the depths. But the man, that is, Michael, was followed by red and various-colored horses, and white ones, with the order, as they think, changed: so that the white ones signify the Medes and the Persians, because under them the captivity was dismissed and the temple was rebuilt; the various-colored ones, the Macedonians, some of whom were friends, others were persecutors (the last vision of Daniel [Chapter 8] speaks most fully on this matter); but the red ones signify the kingdom of the Romans, bloody and murderous, which killed the people and destroyed the temple. But others, preserving the order that was written, interpret the man who rides a red horse and the red horses as representing the four kingdoms. The first and second, the bloodshedders, are interpreted as the Assyrians and Chaldeans, whose first ten tribes were led captive by Salmanasar. The second, Judah and Benjamin, with the city of Jerusalem burned and the temple destroyed. The third and fourth, the various and white horses, are thought to represent the Medes and Persians: some of whom were merciful, such as Cyrus, Darius son of Hystaspis, and Artaxerxes, called by the Greeks Assuerus, under whom the story of Esther is fulfilled; others were cruel, such as Cambyses and the rest. Therefore, the seer and prophet sees a man riding on a red horse, followed by red, spotted, and white horses. Not knowing what he had seen, and desiring to understand the meaning of his vision, he asks, 'What are these, my Lord?' The angel who was speaking with him promises to reveal the answer. As the seer remains silent, a man standing among the myrtle trees recounts, 'These are the kingdoms that the Lord has commanded to go throughout the earth and subdue it under their authority.' Finally, the angels who presided over kingdoms and nations do not come to anyone else, but to the very man and angel of the Lord who stood among the myrtles, and they say: We have walked through the earth, and behold, all the earth is inhabited and at rest. And the meaning is: all the kingdoms under us are safe and peaceful, and no distress weighs upon them. From this response, the angel who interceded for Israel takes the opportunity to pray for the people, and says to the Lord: Since the whole world is quiet and peaceful, why, O Lord, do you not have mercy on Jerusalem and the cities of Judah, especially since the time of captivity, according to your promises, has been fulfilled? And the Lord answered the angel who spoke in the prophet with good words, comforting words. Good words regarding the promises of the future, comforting words regarding the needs of the present. These, according to the letter, so that we may not see our own concealed things, which we have learned from foreign language teachers. But the teachers of the Churches understand the darkness of the mystical vision on the night when the vision is seen. For God has placed darkness as his hiding place (Psalm 18:12). And according to the Septuagint translators, it is said of him: 'The abyss is like his garment' (Ps. 103:6). But the man who was riding on a red horse is the Lord Savior, who, by taking on the dispensation of our flesh, hears in Isaiah: 'Why are your garments red?' (Isa. 63:2). This one who is now shown as red to the captive people is described in the Apocalypse of John as sitting on a white horse, wearing white garments (Rev. 3 and 6). But what is said to be standing between two shady mountains (although in Hebrew it does not have two), the New and Old Testaments understand, which is said to be covered with dense leaves, and forest, and shady woods, because it is enveloped in many obscurities. But the myrtles that were in the depths, among which it is described as standing, understand the angelic powers, which also ministered to him even in the flesh. Or certainly the mountains (to remove what is not written, two) absolutely and without number, we can understand many holy people and apostles and apostolic men, who are reported to have traveled the whole world, red, and various, and white. Some have been crowned with martyrdom and are called 'rufi'. Others, through their works, teaching, and variety of signs, are called by various names. Others have received rewards for their virginity, purity of doctrine, and pure heart that sees God. Finally, the prophet asks the same man and angel who stood among the myrtles, saying: Who are these, my lord? And the angel who spoke in him, namely the prophetic sense, promises to show what is seen. And when he had promised, he did not answer himself, but another who stood among the myrtle trees, and said: These are the ones whom the Lord has sent to walk the earth. For the apostles were sent by the Lord to complete the preaching of the Gospel throughout the whole world, and after they had fulfilled their mission, they returned to the angel of the great council who stood among them, who spoke with the Apostle: We are the pleasing aroma of Christ to those who are being saved and to those who are perishing (1 Corinthians 2:15), and among peoples of both callings. And they said to him: We have traveled the land, fulfilled the work that was assigned to us, and behold, the whole land is inhabited and at rest, which was once deserted by God. Now it is His dwelling place, resting from wars, battles of vices and sins. For He has received the inheritance of the Lord, who has returned to the Father, and who says: My peace I give to you, my peace I leave you (John 14:27). And as for the full mercy that is requested, they refer to the imminent seventieth year when God will have mercy on Jerusalem and the cities of Judah, with respect to that understanding: that as long as true peace comes and the Sabbath and the number of seven decades, that is, the seventieth year is fulfilled, neither Jerusalem may receive complete freedom, which is interpreted as the vision of peace and is the Church, nor may the cities of Judah, who confess the Lord, receive it. Finally, the Lord promises good words, consoling words: which we now see in part, and in part we prophesy (I Cor. XIII, 12). But when that which is perfect has come, those things which are in part will be done away with: and being delivered from the Babylon of this age, let us cry out: When the Lord brings back the captivity of Zion, we became like those consoled (Psal. CXXV, 1).

[AD 420] Jerome on Zechariah 1:9
“I will hear what the Lord God proclaims in me.” The prophet is praying for the people and speaks while God is speaking in him: “I will listen to what the Lord God is proclaiming in me.” You perceive that God does not speak in the ears but in the heart, as Zechariah says: “The angel who spoke in me answered me.” The angel is understood to be our Lord, who is proclaiming the will of the Father and who, in Isaiah, is called the angel of the great counsel. I will listen to the voice of the Lord God within me; I shall attend with the ear of my heart that I may hear what the Lord God speaks in me.

[AD 430] Augustine of Hippo on Zechariah 1:9
Likewise, who will tell with what bodies angels appear to people, in such fashion as not to be visible but to be tangible? And again how, not through tangible corporeality but by spiritual power, angels produce certain visions, not to the eyes of the body but to those of the spirit or the mind, or can utter speech, not of the ear from without, but within the soul of humans, being themselves placed there, as is written in the book of the prophets: “And the angel that spoke in me said to me” (for what the prophet says is not “that spoke to me,” but “in me”).… They appear also in sleep and speak through dreams (for we read in the Gospel: “Behold, an angel of the Lord appeared to him in a dream, saying”). These methods of communication tend to show that the angels have intangible bodies, and make it a very difficult question how the patriarchs could wash the feet of angels, and how Jacob could wrestle with an angel in contact so unmistakable. Asking these questions and answering them with such guesses as we can is not a useless exercise for the mind, if the discussion is kept within bounds and if those who take part avoid the error of thinking they know what they do not know. For what need is there of affirming or denying or making nice distinctions about these and similar matters, when ignorance of them imputes no blame?
