For some time back I had paid special attention to the book of Genesis; and I had got aid in the analysis of it from a German volume. That it was based on _at least_ two different documents, technically called the Elohistic and Jehovistic, soon became clear to me: and an orthodox friend who acknowledged the fact, regarded it as a high recommendation of the book, that it was conscientiously made out of pre-existing materials, and was not a fancy that came from the brain of Moses. My good friend's argument was not a happy one: no written record could exist of things and times which preceded the invention of writing. After analysing this book with great minuteness, I now proceeded to Exodus and Numbers; and was soon assured, that these had not, any more than Genesis, come forth from one primitive witness of the facts. In all these books is found the striking phenomenon of _duplicate_ or even _triplicate narratives_. The creation of man is three times told. The account of the Flood is made up out of two discrepant originals, marked by the names Elohim and Jehovah; of which one makes Noah take into the ark _seven_ pairs of clean, and _single_ (or double?) pairs of unclean, beasts; while the other gives him two and two of all kinds, without distinguishing the clean. The two documents may indeed in this narrative be almost re-discovered by mechanical separation. The triple statement of Abraham and Isaac passing off a wife for a sister was next in interest; and here also the two which concern Abraham are contrasted as Jehovistic and Elohistic. A similar double account is given of the origin of circumcision, of the names Isaac, Israel, Bethel, Beersheba. Still more was I struck by the positive declaration in Exodus (vi. 3) that _God was_ NOT _known to Abraham, Isaac, and Jacob by the name Jehovah_; while the book of Genesis abounds with the contrary fact. This alone convinced me beyond all dispute, that these books did not come from one and the same hand, but are conglomerates formed out of older materials, unartistically and mechanically joined. Indeed a fuller examination showed in Exodus and Numbers a twofold miracle of the quails, of which the latter is so told as to indicate entire unacquaintance with the former. There is a double description of the manna, a needless second appointment of Elders of the congregation: water is twice brought out of the rock by the rod of Moses, whose faith is perfect the first time and fails the second time. The name of Meribah is twice bestowed. There is a double promise of a guardian angel, a double consecration of Aaron and his sons: indeed, I seemed to find a double or even threefold[4] copy of the Decalogue. Comprising Deuteronomy within my view, I met two utterly incompatible accounts of Aaron's death; for Deuteronomy makes him die _before_ reaching Meribah Kadesh, where, according to Numbers, he sinned and incurred the penalty of death (Num. xx. 24, Deut x. 6: cf Num. xxxiii. 31, 38).
