Daniel 9:1
1In the first year of Darius the son of Ahasuerus, of the offspring of the Medes, who was made king over the realm of the Chaldeans—
Wesley dates the prayer to the first year of Darius the Mede—immediately after Babylon’s fall, the year of the Jews’ deliverance from captivity. He will not let this Darius be confused with Darius the Persian, as if the book’s setting were a later invention. The date is historical, and the man who prays is the Daniel who lived through the empire’s change.
Arminian readers read the opening as a moment in an exile. God has overturned Babylon; the prophet is still a servant in a foreign court. Nothing here is a debate about works earning mercy. It is a man named among a people, turning toward the God who had promised an end to desolations.
Calvin hears two movements in the chapter: how ardently Daniel prayed as Jeremiah’s time of redemption drew near, and the answer he received. The first year of Darius is not ornament. When the monarchy passed to the Medes and Persians, the hour named by Jeremiah was at the door.
Reformed readers take the date as providence, not coincidence. God had fixed seventy years; he also arranged the change of empires. Daniel’s prayer will not invent a new timetable. It will take the promise as already spoken and ask the Lord to do what he said.
