Genesis 6:10

And Noah begat three sons, Shem, Ham, and Japheth (cf. Genesis 5:32 ). Here (in the story of the Flood) if anywhere, observes Rosenmüller, can traces be detected of two distinct documents ( duorum monumentorum ), in the alternate use of the names of the Deity, the frequent repetitions of the same things, and the use of peculiar forms of expression; and in Genesis 6:9-13 , compared with Genesis 6:5-8 , Bleek, Tuch, Colenso, and others find' the first instance of needless repetition, on the supposition of the unity of the narrative, but a sure index of the Elohistic pen, on the hypothesis of different authors; but the so-called "repetition" is explained by remembering that Genesis 6:5-8 forms the close of a section "bringing down the history to the point at which the degeneracy of mankind causes God to resolve on the destruction of the world," while the new section, which otherwise would begin too abruptly, introduces the account of the Deluge by a brief description of its cause. The structure of the narrative here is not different from what it appears elsewhere (cf. Genesis 2:4 ; Genesis 5:1 ).
