7 Upon the four and twentieth day of the eleventh month, which is the month Sebat, in the second year of Darius, came the word of the LORD unto Zechariah, the son of Berechiah, the son of Iddo the prophet, saying,
[AD 420] Jerome on Zechariah 1:7
(Vrs. 7.) On the twenty-fourth day of the eleventh month, which is the month Sabat, in the second year of Darius, the word of the Lord came to Zechariah, the son of Barachiah, the son of Addo, the prophet, saying. LXX: On the twenty-fourth day of the eleventh month, which is the month Sabat, in the second year under Darius, the word of the Lord came to the prophet Zechariah, the son of Barachiah, the son of Addo, saying. Some place the eleventh month as the twelfth month and interpret the twenty-fourth day of the same month by mathematical calculations, suspecting it to be a firm and stable number, wanting what is written to be certain and stable; but we say that in the same year, the second year of King Darius, in the third month after the first Vision, that is, the eleventh month after the eighth, which is called Sabat by the Hebrews, again the word of the Lord came to Zechariah. According to the number, it is unclean and pertains to the union of flesh and worldly things, pertaining to matter, as we often teach. But the eleventh month, which is called Sabat, and is translated in our language as "rod," signifies severity and chastisement, as the Apostle says: What do you want? Shall I come to you with a rod? (1 Corinthians 4:21). And as the Psalmist says: Your rod and your staff, they comfort me (Psalm 23:4). And it is during the harshest time of winter, which is called Mechir by the Egyptians, περίτιος by the Macedonians, and Februarius by the Romans. The twenty-fourth day of the month also signifies the illustrious shadow of the night, with the moon waning into darkness and the blind and perpetual horror of the night growing. Therefore, it is fitting that those who were still in captivity, the majority of whom were in Media and Chaldea, and were exiled in Assyria, saw what follows on the second year and eleventh month, during the most severe cold, and on the twenty-fourth day of the same month, to the Jewish people.

[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.
