Now in the first year of Cyrus, king of Persia This is that famous Cyrus who, one hundred and forty years before the temple was destroyed, and two hundred years before he was born, was mentioned by name in the prophecies of Isaiah, as raised up, and appointed by God, for the restoration of his people, Isaiah 44:28; Isaiah 45:1; Isaiah 45:4. This remarkable prediction, it is probable, Daniel showed to Cyrus, and that it induced him to give forth the following edict. So Prideaux thinks, with many other learned men. Cyrus, it appears, at his first coming to Babylon, found Daniel there, an old minister of state, famed for his great wisdom over all the East; and hence he not only himself employed him as such, but, upon settling the government, made him first superintendent, or prime minister of state, over all the provinces of the empire. In this station of life Daniel must have been a person of great authority at court, and highly in the esteem of his prince; and, as there could be no doubt but he would use his good offices in behalf of the enlargement of the Jews, so it is not likely he should use them in vain, especially if he showed Cyrus the prophecies just mentioned, which, it is evident from the decree itself, that Cyrus had seen. It must be observed that, strictly speaking, this decree was not given forth in the first year of Cyrus's reign; for then the Jews were not his subjects; but in the first year after his conquest of Babylon, where the Jews then lived in captivity.
That the word of the Lord by the mouth of Jeremiah might be fulfilled Who foretold that after seventy years the king of Babylon and the Chaldeans should be destroyed, and the people of Judah restored to their own land. This prophecy was first delivered in the fourth year of Jehoiakim, the son of Josiah, which was the first year of Nebuchadnezzar; and the same year Nebuchadnezzar invaded Judea, besieged and took Jerusalem, made Jehoiakim his subject and tributary, transported the finest children of the royal family and of the nobility to Babylon, to be bred up there for eunuchs and slaves in his palace, and also carried away the vessels of the house of the Lord and put them in the temple of his god at Babylon. Seventy years from this time will bring us down to the first year of Cyrus, (2 Chronicles 36:22; Ezra 1:3,) when he made his proclamation for the restoration of the Jews, and for the building of the temple at Jerusalem. This computation of the seventy years captivity appears to many to be the truest and most agreeable to Scripture. But, if we fix the commencement of these seventy years at the time when Jerusalem was burned and destroyed, their conclusion will fall about the time when Darius issued his decree for rebuilding the temple, after the work had been suspended and stopped. Or, if we fix their commencement at the time when Nebuzaradan carried away the last remainder of the people, and completed the desolation of the land, their conclusion will fall about the time when the temple was finished and dedicated, and the first passover was solemnized in it. “So that,” as Dean Prideaux says, “taking it which way we will, and at what stage we please, the prophecy of Jeremiah will be fully and exactly accomplished concerning this matter.” It may be said to have been accomplished, indeed, at three different times, and in three different manners, and therefore, possibly, all might have been intended, though the first, without doubt, was the principal subject of the prophecy.
The Lord stirred up the spirit of Cyrus, king of Persia God, who had long before designed him for this work, now suggested these thoughts and intentions to him, and excited him to begin to prosecute them, (for it was not all accomplished in the first year of Cyrus,) which he did, not only by causing his will and pleasure to be proclaimed, but to be put in writing, that none might mistake his meaning.
