he had done all that God commanded him, _vv_. 22, 18.
[Footnote 1: Wrongly represented by _the Lord_ in the English
version; the American Revised Version always correctly renders by
_Jehovah_. _God_ in v. 5 is an unfortunate mistake of A.V.
This ought also to be _the Lord_, or rather _Jehovah_.]

But, to our surprise, ch. vii. starts the whole story afresh with a
divine command to Noah to enter the ark; and this time, significantly
enough, a distinction is made between the clean and the unclean-seven
pairs of the former to enter and one pair of the latter (vii. 2). It
is surely no accident that in this section the name of the divine
Being is Jehovah, _vv_. 1, 5; and its contents follow naturally
on vi. 5-8. In other words we have here, not a continuous account,
but two parallel accounts, one of which uses the name God, the other
Jehovah, for the divine Being. This important conclusion is put
practically beyond all doubt by the similarity between vi. 22 and vii. 5,
which differ only in the use of the divine name. A close study of the
characteristics of these sections whose origin is thus certain will
enable us approximately to relegate to their respective sources other
sections, verses, or fragments of verses in which the important clue,
furnished by the name of the divine Being, is not present. Any verse,
or group of verses, e.g. involving the distinction between the clean
and the unclean, will belong to the _Jehovistic_ source, as it is
called (J). This is the real explanation of the confusion which
every one feels who attempts to understand the story as a unity. It
was always particularly hard to reconcile the apparently conflicting
estimates of the duration of the Flood; but as soon as the sources
are separated, it becomes clear that, according to the Jehovist, it
lasted sixty-eight days, according to the other source over a year
(vii. 11, viii. 14).
