1. This passage, therefore, as it stands thus, touches on many marvellous things. At present, however, I shall speak only of those things in it which bear upon chronology, and matters connected therewith. That the passage speaks then of the advent of Christ, who was to manifest Himself after seventy weeks, is evident. For in the Saviour's time, or from Him, are transgressions abrogated, and sins brought to an end. And through remission, moreover, are iniquities, along with offences, blotted out by expiation; and an everlasting righteousness is preached, different from that which is by the law, and visions and prophecies (are) until John, and the Most Holy is anointed. For before the advent of the Saviour these things were not yet, and were therefore only looked for. And the beginning of the numbers, that is, of the seventy weeks which make up 490 years, the angel instructs us to take from the going forth of the commandment to answer and to build Jerusalem. And this happened in the twentieth year of the reign of Artaxerxes king of Persia. For Nehemiah his cup-bearer besought him, and received the answer that Jerusalem should be built. And the word went forth commanding these things; for up to that time the city was desolate. For when Cyrus, after the seventy years' captivity, gave free permission to all to return who desired it, some of them under the leadership of Jesus the high priest and Zorobabel, and others after these under the leadership of Esdra, returned, but were prevented at first from building the temple, and from surrounding the city with a wall, on the plea that that had not been commanded.

2. It remained in this position, accordingly, until Nehemiah and the reign of Artaxerxes, and the 115th year of the sovereignty of the Persians. And from the capture of Jerusalem that makes 185 years. And at that time King Artaxerxes gave order that the city should be built; and Nehemiah being despatched, superintended the work, and the street and the surrounding wall were built, as had been prophesied. And reckoning from that point, we make up seventy weeks to the time of Christ. For if we begin to reckon from any other point, and not from this, the periods will not correspond, and very many odd results will meet us. For if we begin the calculation of the seventy weeks from Cyrus and the first restoration, there will be upwards of one hundred years too many, and there will be a larger number if we begin from the day on which the angel gave the prophecy to Daniel, and a much larger number still if we begin from the commencement of the captivity. For we find the sovereignty of the Persians comprising a period of 230 years, and that of the Macedonians extending over 370 years, and from that to the 16th [1115] year of Tiberius Cæsar is a period of about 60 years.

3. It is by calculating from Artaxerxes, therefore, up to the time of Christ that the seventy weeks are made up, according to the numeration of the Jews. For from Nehemiah, who was despatched by Artaxerxes to build Jerusalem in the 115th year of the Persian empire, and the 4th year of the 83d Olympiad, and the 20th year of the reign of Artaxerxes himself, up to this date, which was the second year of the 202d Olympiad, and the 16th year of the reign of Tiberius Cæsar, there are reckoned 475 years, which make 490 according to the Hebrew numeration, as they measure the years by the course of the moon; so that, as is easy to show, their year consists of 354 days, while the solar year has 365¼ days. For the latter exceeds the period of twelve months, according to the moon's course, by 11¼ days. Hence the Greeks and the Jews insert three intercalary months every 8 years. For 8 times 11¼ days makes up 3 months. Therefore 475 years make 59 periods of 8 years each, and 3 months besides. But since thus there are 3 intercalary months every 8 years, we get thus 15 years minus a few days; and these being added to the 475 years, make up in all the 70 weeks.
