Daniel 9:2 - Coke's Commentary on the Holy Bible

I Daniel understood by books— Daniel had with him in the captivity the holy Scriptures, and in particular the prophesies of Jeremiah, which he here calls so many books: he refers more particularly to the 25th and 29th Chapter s of that prophet. We may hence observe, that the later prophets studied the writings of the former, for the more perfect understanding of the times when their prophesies were to be fulfilled. Daniel saw a part of Jeremiah's prediction fulfilled, by the vengeance which the Lord had taken upon the house of Nebuchadnezzar; but he saw no appearance of that deliverance of the people of Israel which the prophet foretold. This was the cause of his uneasiness, and the motive of his prayers.
