23. Now in the first year of Cyrus king of Persia,.... These two verses are the same with which the next book, the book of Ezra, begins, where they will be explained; and these two books, the one ending and the other beginning with the same words, is a strong presumption, that one and the same person, Ezra, is the writer of them both; or rather, as a learned writer conjectures, these two verses are added by some transcriber, who, having finished the book of Chronicles at verse twenty one went on with the book of Ezra, without any stop; but, perceiving his mistake, broke off abruptly; for so it is plain these verses conclude; however, this shows, as the same writer observes, that the book of Ezra followed that of the Chronicles, in the Hebrew copies, though it now does not.
