in the first year of his reign, I, Daniel, have understood by books the number of the years, (in that a word of Jehovah hath been unto Jeremiah the prophet,) concerning the fulfilling of the wastes of Jerusalem, seventy years;

In the first year of his rule, I, Daniel, saw clearly from the books the number of years given by the word of the Lord to the prophet Jeremiah, in which the making waste of Jerusalem was to be complete, that is, seventy years.

In anno primo, inquam, [79] regni illius, ego Daniel intellexi in libris numerum annorum, de quibus fuerat sermo Jehovae, ad ad Jeremiam prophetam, [80] ad implendum desolationem Jerusalem annos septuaginta.

I Daniel understood by books - By the sacred books, and especially by the writings of Jeremiah. It has been made a ground of objection to the genuineness of Daniel that he mentions "books" in this place (ספרים sephârı̂ym) as if there were at that time a collection of the sacred books, or as if they had been enrolled together in a volume. The objection is, that the writer speaks as if the canon of the Scriptures was completed, or that he uses such language as the Hebrews did when the canon of the Scriptures was finished, and thus betrays himself. See Bertholdt, "Commentary" p. 78. Compare DeWette, "Einl." Section 13. This objection has been examined by Hengstenberg, "Beitrag." pp. 32-35. It is sufficient to reply to it, that there is every probability that the Jews in Babylon would be in possession of the sacred books of their nation, and that, though the canon of the Scriptures was not yet completed, there would exist private collections of those writings. The word used here by Daniel is just such as he would employ on the supposition that he referred to a private collection of the writings of the prophets. Compare Lengerke, in loc. See the Introduction, where the objection is examined.
The number of the years, whereof the word of the Lord came to Jeremiah - The number of the years in respect to which the word of the Lord came to Jeremiah; that is, which he had revealed to Jeremiah. The "books" referred to, therefore, were evidently a collection of the writings of Jeremiah, or a collection which embraced his writings.
That he would accomplish seventy years in the desolations of Jerusalem - That Jerusalem would so long lie waste. This was expressly declared by Jeremiah Jeremiah 25:11-12 : "And this whole land shall be a desolation and an astonishment; and these nations shall serve the king of Babylon seventy years. And it shall come to pass, when seventy years are accomplished, that I will punish the king of Babylon, and that nation, saith the Lord, for their iniquity," etc. So also Jeremiah 29:10 : "For thus saith the Lord, That after seventy years be accomplished at Babylon, I will visit you, and perform my good word toward you, in causing you to return to this place." The time of the desolation and of the captivity, therefore, was fixed and positive, and the only difficulty in determining when it would "close," was in ascertaining the exact year when it "commenced." There were several occurrences which might, perhaps, be regarded as the beginning of the desolations and the captivity - the "terminus a quo" - and, according as one or another of them was fixed on, the close would be regarded as nearer or more remote.
Daniel, it seems, by close study, had satisfied his own mind on that subject, and had been able to fix upon some period that was undoubtedly the proper beginning, and hence, compute the time when it would close. The result showed that his calculation was correct, for, at the time he expected, the order was given by Cyrus to rebuild the city and temple. When he instituted this inquiry, and engaged in this solemn act of prayer, it would have been impossible to have conjectured in what way this could be brought about. The reigning monarch was Cyaxares II, or, as he is here called, Darius, and there was nothing in "his" character, or in anything that he had done, that could have been a basis of calculation that he would favor the return of the Jews and the rebuilding of the city, and there was then no probability that Cyrus would so soon come to the throne, and nothing in his character, as known, that could be a ground of hope that he would voluntarily interpose, and accomplish the Divine purposes and promises in regard to the holy city. It was probably such circumstances as these which produced the anxiety in the mind of Daniel, and which led him to offer this fervent prayer; and his fervent supplications should lead us to trust in God that he will accomplish his purposes, and should induce us to pray with fervour and with faith when we see no way in which he will do it. In all cases he can as easily devise a way in answer to prayer, as he could remove Cyaxares from the throne, and incline the heart of Cyrus to undertake the rebuilding of Jerusalem and the temple.

I Daniel understood by books - The prophecy referred to here is found Jeremiah 25:12; Jeremiah 29:10. The people must have been satisfied of the Divine inspiration of Jeremiah, or his prophecies would not have been so speedily collected nor so carefully preserved. It appears that there was a copy of them then in Daniel's hands.

In the first year of his reign I Daniel understood by (c) books the number of the years, whereof the word of the LORD came to Jeremiah the prophet, that he would accomplish seventy years in the desolations of Jerusalem.
(c) For even though he was an excellent Prophet, yet he daily increased in knowledge by the reading of the scriptures.

In the first year of his reign,.... Which was also the first of Cyrus, who was partner with him in the kingdom; in which year ended the seventy years' captivity of the Jews, and proclamation was made to have their liberty to go up to Jerusalem, and build the temple, Ezra 1:1, reckoning from the third, or the beginning of the fourth, of Jehoiakim king of Judah, when the desolation of the land began, and Daniel himself was carried captive; and which was the first year of Nebuchadnezzar king of Babylon, during whose reign, and that of his son, and son's son, the Jews were to be detained captives, Daniel 1:1.
I Daniel understood by books; the sacred Scriptures, which, though a prophet, he was not above reading; and, though a prime minister of state, yet found time to look into these divine oracles; which he read, studied, thoroughly considered, and well weighed in his mind; whereby he came to have knowledge of
the number of the years whereof the word of the Lord came to Jeremiah the prophet, that he would accomplish seventy years in the desolations of Jerusalem; Daniel might possibly have heard this prophecy of Jeremiah from his own mouth, before he went to Babylon; since the first intimation of it was in the first year of Jehoiakim, Jeremiah 27:1, and after this the prophecy might be sent to Babylon for the use of the captive Jews there; and indeed a copy of all his prophecies was no doubt brought thither at the last captivity of the people; so that it is easy to account for it how Daniel came by it; and it is plain it was now before him; for he uses the very word, "desolations", which Jeremiah does, Jeremiah 25:9, the prophecy of the seventy years' captivity, and of deliverance from it at the expiration of that term, stands in Jeremiah 25:12, which Daniel carefully read over, thoroughly considered, and as he full well knew what was the epoch of them, or when they begun, he found that they were just ready to expire; and this set him to the work of prayer, as in the following verses. From hence it is manifest that the law was not burnt, nor the Scriptures lost, in the Babylonish captivity; so that none knew what were or would be done by the Lord, as is falsely asserted in the Apocrypha:
"For thy law is burnt, therefore no man knoweth the things that are done of thee, or the work that shall begin. &c.'' (2 Esdras 14:21)

understood by books--rather, "letters," that is, Jeremiah's letter (Jeremiah 29:10) to the captives in Babylon; also Jeremiah 25:11-12; compare 2-Chronicles 36:21; Jeremiah 30:18; Jeremiah 31:38. God's promises are the ground on which we should, like Daniel, rest sure hope; not so as to make our prayers needless, but rather to encourage them.
