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 she 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.
