(1) In the former chapter we treated of the foundations and principles of Scriptural knowledge, and showed that it consists solely in a trustworthy history of the sacred writings; such a history, in spite of its indispensability, the ancients neglected, or at any rate, whatever they may have written or handed down has perished in the lapse of time, consequently the groundwork for such an investigation is to a great extent, cut from under us. (2) This might be put up with if succeeding generations had confined themselves within the limits of truth, and had handed down conscientiously what few particulars they had received or discovered without any additions from their own brains: as it is, the history of the Bible is not so much imperfect as untrustworthy: the foundations are not only too scanty for building upon, but are also unsound. (3) It is part of my purpose to remedy these defects, and to remove common theological prejudices. (4) But I fear that I am attempting my task too late, for men have arrived at the pitch of not suffering contradiction, but defending obstinately whatever they have adopted under the name of religion. (5) So widely have these prejudices taken possession of men's minds, that very few, comparatively speaking, will listen to reason. (6) However, I will make the attempt, and spare no efforts, for there is no positive reason for despairing of success. (7) In order to treat the subject methodically, I will begin with the received opinions concerning the true authors of the sacred books, and in the first place, speak of the author of the Pentateuch, who is almost universally supposed to have been Moses. (8) The Pharisees are so firmly convinced of his identity, that they account as a heretic anyone who differs from them on the subject. (9) Wherefore, Aben Ezra, a man of enlightened intelligence, and no small learning, who was the first, so far as I know, to treat of this opinion, dared not express his meaning openly, but confined himself to dark hints which I shall not scruple to elucidate, thus throwing full light on the subject. (10) The words of Aben Ezra which occur in his commentary on Deuteronomy are as follows: "Beyond Jordan, &c . . . If so be that thou understandest the mystery of the twelve . . . moreover Moses wrote the law . . . The Canaanite was then in the land . . . . it shall be revealed on the mount of God . . . . then also behold his bed, his iron bed, then shalt thou know the truth." (11) In these few words he hints, and also shows that it was not Moses who wrote the Pentateuch, but someone who lived long after him, and further, that the book which Moses wrote was something different from any now extant. (12) To prove this, I say, he draws attention to the facts: (13) 1. That the preface to Deuteronomy could not have been written by Moses, inasmuch as he ad never crossed the Jordan.
