Daniel 9:2

“In the first year of his reign, etc.] 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, (<150101>Ezra 1:1,2), 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, (<270101>Daniel 1:1 <242501>Jeremiah 25:1 27:1). I Daniel understood by books; the…”

“understood by books--rather, "letters," that is, Jeremiah's letter (Jer 29:10) to the captives in Babylon; also Jer 25:11-12; compare Ch2 36:21; Jer 30:18; Jer 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.”

“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…”

“By books - By the sacred books. Daniel 9:12”

“9:2 reading . . . Jeremiah: Daniel apparently had a copy of Jeremiah’s prophecies. • Jerusalem must lie desolate for seventy years: Jerusalem was destroyed in 586 BC (see 2 Kgs 25:8), and the first return occurred in 538 BC—about 48 years later. The rebuilding of the city began almost at once (see Ezra 3:1-13; Isa 44:28), and the rebuilt Temple was completed in 515 BC—about seventy-one years after it was destroyed (Ezra 6:15). Daniel might have thought of Jerusalem’s “destruction” as having begun with his own exile in 605 BC (see Jer 25:11-12), with sixty-seven years between 605 and 538 BC.”
