Introduction to 1 Chronicles

The books of Chronicles are, in a great measure, repetitions of what is in the books of Samuel and of the Kings, yet there are some excellent useful things in them which we find not elsewhere. The FIRST BOOK traces the rise of the Jewish people from Adam, and afterward gives an account of the reign of David. In the SECOND BOOK the narrative is continued, and relates the progress and end of the kingdom of Judah; also it notices the return of the Jews from the Babylonish captivity. Jerome says, that whoever supposes himself to have knowledge of the Scriptures without being acquainted with the books of Chronicles, deceives himself. Historical facts passed over elsewhere, names, and the connexion of passages are to be found here, and many questions concerning the gospel are explained.
