IN English ears it must sound pedantic to speak of "weeks" in any other than the familiar acceptation of the term. But with the Jew it was far otherwise. The effect of his laws was fitted "to render the word week capable of meaning a seven of years almost as naturally as a seven of days. Indeed the generality of the word would have this effect at any rate. Hence its use to denote the latter in prophecy is not mere arbitrary symbolism, but the employment of a not unfamiliar and easily understood language."^[1]

     Daniel's prayer referred to seventy years fulfilled: the prophecy which came in answer to that prayer foretold a period of seven times seventy still to come. But here a question arises which never has received sufficient notice in the consideration of this subject. None will doubt that the era is a period of years; but of what kind of year is it composed? That the Jewish year was lunisolar appears to be reasonably certain. If tradition may be trusted, Abraham preserved in his family the year of 360 days, which he had known in his Chaldean home.^[2] The month dates of the flood (150 days being specified as the interval between the seventeenth day of the second month, and the same day of the seventh month) appear to show that this form of year was the earliest known to our race. Sir Isaac Newton states, that "all nations, before the just length of the solar year was known, reckoned months by the course of the moon, and years by the return of winter and summer, spring and autumn; and in making calendars for their festivals, they reckoned thirty days to a lunar month, and twelve lunar months to a year, taking the nearest round numbers, whence came the division of the ecliptic into 360 degrees." And in adopting this statement, Sir G. C. Lewis avers that "all credible testimony and all antecedent probability lead to the result that a solar year containing twelve lunar months, determined within certain limits of error, has been generally recognized by the nations adjoining the Mediterranean, from a remote antiquity."^[3]

     One of the characteristic ordinances of the Jewish law was, that every seventh year the land was to lie fallow, and it was in relation to the neglect of this ordinance that the era of the desolations was decreed. It was to last "until the land had enjoyed her Sabbaths; for so long as she lay desolate, she kept Sabbath, to fulfill threescore and ten years." (2 Chronicles 36:21; cf. Leviticus 26:34, 35) The essential element in the judgment was, not a ruined city, but a land laid desolate by the terrible scourge of a hostile invasion, (Compare Jeremiah 27:13; Haggai 2:17) the effects of which were perpetuated by famine and pestilence, the continuing proofs of the Divine displeasure. It is obvious therefore, that the true epoch of the judgment is not, as has been generally assumed, the capture of Jerusalem, but the invasion of Judea. From the time the Babylonian armies entered the land, all agricultural pursuits were suspended, and therefore the desolations may be reckoned from the day the capital was invested, namely, the tenth day of the tenth month in the ninth year of Zedekiah. This was the epoch as revealed to Ezekiel the prophet in his exile on the banks of the Euphrates, (Ezekiel 24:1, 2) and for twenty-four centuries the day has been observed as a fast by the Jews in every land.

     The close of the era is indicated in Scripture with equal definiteness, as "the four-and-twentieth day of the ninth month in the second year of Darius.^[4] "Consider now" (the prophetic word declared) "from this day and upward – from the four-and- twentieth day of the ninth month, even from the day that the foundation of the Lord's temple was laid – consider it: from this day I will bless you." Now from the tenth day of Tebeth B.C. 589,^[5] to the twenty-fourth day of Chisleu B.C. 520,^[6] was a period of 25, 202 days; and seventy years of 360 days contain exactly 25, 200 days. We may conclude, therefore, that the era of the "desolations" was a period of seventy years of 360 days, beginning the day after the Babylonian army invested Jerusalem, and ending the day before the foundation of the second temple was laid.^[7]

     But this inquiry may be pressed still further. As the era of the "desolations" was fixed at seventy years, because of the neglect of the Sabbatic years, (2 Chronicles 36:21; Leviticus 26:34, 35) we might expect to find that a period of seven times seventy years measured back from the close of the seventy years of "indignation against Judah," would bring us to the time when Israel entered into their full national privileges, and thus incurred their full responsibilities. And such in fact will be found upon inquiry to be the case. From the year succeeding the dedication of Solomon's temple, to the year before the foundation of the second temple was laid, was a period of 490 years of 360 days.^[8]

     As already noticed, the prophetic era is divided into two periods, the one of 7+ 62 heptades, the other of a single heptade.^[10] Connected with these eras, two "princes" are prominently mentioned; first, the Messiah, and secondly, a prince of that people by whom Jerusalem was to be destroyed, – a personage of such pre-eminence, that on his advent his identity is to be as certain as that of Christ Himself. The first era closes with the "cutting off" of Messiah; the beginning of the second era dates from the signature of a "covenant," or treaty, by this second "prince," with or perhaps in favor of "the many,"^[11] that is the Jewish nation, as distinguished probably from a section of pious persons among them who will stand aloof. In the middle of the heptade the treaty is to be violated by the suppression of the Jews' religion, and a time of persecution is to follow.

     It is not impossible, of course, that prophecy may foretell the career of two different men, answering the same description, who will pursue a precisely similar course in similar circumstances for a similar period of three and a half years; but the more natural and obvious supposition is that the two are identical. Owing to the very nature of the subject, their identity cannot be logically demonstrated, but it rests upon precisely the same kind of proof upon which juries convict men of crimes, and convicted prisoners are punished.

     Now this seventieth week is admittedly a period of seven years, and half of this period is three times described as "a time, times, and half a time," or "the dividing of a time;" (Daniel 7:25; 12:7; Revelation 12:14) twice as forty-two months; (Revelation 11:2; 13:5) and twice as 1, 260 days. (Revelation 11:3; 12:6) But 1, 260 days are exactly equal to forty-two months of thirty days, or three and a half years of 360 days, whereas three and a half Julian years contain 1, 278 days. It follows therefore that the prophetic year is not the Julian year, but the ancient year of 360 days.^[12]

7. The date of the Paschal new moon, by which the Jewish year is regulated, was the evening of the 14th March in B. C. 589, and about noon on 1st April B. C. 520. According to the phases the 1st Nisan in the former year was probably the 15th or 16th March, and in the latter the 1st or 2nd April.

8. The temple was dedicated in the eleventh year of Solomon, and the second temple was founded in B. C. 520. The intervening period reckoned exclusively was 483 years = 490 lunisolar years of 360 days. It is noteworthy that the interval between the dedication of Solomon's temple and the dedication of the second temple (B. C. 515) was 490 years. A like period had elapsed between the entrance into Canaan and the foundation of the kingdom under Saul. These cycles of 70, and multiples of 70, in Hebrew history are striking and interesting. See App. 1.

9. Though it is signally confirmed by the undoubted fact that the Jewish Sabbatical year was conterminous, not with the solar, but with the ecclesiastical year.

10. The division of the 69 weeks into 7 +62 is accounted for by the fact that the first 49 years, during which the restoration of Jerusalem was completed, ended with a great crisis in Jewish history, the close of the prophetic testimony. Forty-nine years from B. C. 445 brings us to the date of Malachi's prophecy.

12. It is noteworthy that the prophecy was given at Babylon, and the Babylonian year consisted of twelve months of thirty days. That the prophetic year is not the ordinary year is no new discovery. It was noticed sixteen centuries ago by Julius Africanus in his Chronography, wherein he explains the seventy weeks to be weeks of Jewish (lunar) years, beginning with the twentieth of Artaxerxes, the fourth year of the 83rd Olympiad, and ending in the second year of the 202nd Olympiad; 475 Julian years being equal to 490 lunar years.
